Huge WSDL produce a jdk.internal.org.objectweb.asm.MethodTooLargeException

There is a wsdl that is huge. https://raw.githubusercontent.com/attester/virtualbox-soap/master/sdk-files/vboxweb.wsdl The wsdl has a portType (vboxPortType) having about 10.000 lines of code. The wsdl generate a java-interface (org.virtualbox.service.VboxPortType) having 35k lines / 1800 methods. This is the stacktrace:

InvocationTargetException using JCI

I try to run a simple main to compile(!) some java code. This is my pom:

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

And this is my main-class:

package a;

import java.nio.charset.StandardCharsets;

import org.apache.commons.jci.compilers.*;
import org.apache.commons.jci.readers.MemoryResourceReader;
import org.apache.commons.jci.stores.MemoryResourceStore;

        JavaCompilerFactory cf = new JavaCompilerFactory();
        JavaCompiler compiler = cf.createCompiler("javac");
        MemoryResourceReader pReader = new MemoryResourceReader();
        int i = 0;
        pReader.add("Test.java", "class Test{}".getBytes(StandardCharsets.UTF_8));
        MemoryResourceStore pStore = new MemoryResourceStore();
        CompilationResult result = compiler.compile(new String[] { pReader.list()[0] }, pReader, pStore,
                Test.class.getClassLoader());
        System.out.println(result.getErrors()[0]);
    }
}

package a;

import java.nio.charset.StandardCharsets;

import org.apache.commons.jci.compilers.*;
import org.apache.commons.jci.readers.MemoryResourceReader;
import org.apache.commons.jci.stores.MemoryResourceStore;

public class Test {
    public static void main(final String[] args) {
        JavaCompilerFactory cf = new JavaCompilerFactory();
        JavaCompiler compiler = cf.createCompiler("javac");
        MemoryResourceReader pReader = new MemoryResourceReader();
        int i = 0;
        pReader.add("Test.java", "class Test{}".getBytes(StandardCharsets.UTF_8));
        MemoryResourceStore pStore = new MemoryResourceStore();
        CompilationResult result = compiler.compile(new String[] { pReader.list()[0] }, pReader, pStore,
                Test.class.getClassLoader());
        System.out.println(result.getErrors()[0]);
    }
}

My output is: (0:0) : Error while executing the compiler: java.lang.reflect.InvocationTargetException What am I doing wrong?

Switch from commons-fileupload to commons-fileupload-jakarta-servlet6

I need to change my fileupload-integration to the jakarta6-version. The old code is

        resp.setHeader("Transfer-Encoding", "chunked");
        byte timeout = parseTimeoutParameter(req);
        int port = parsePortParameter(req);
        long expLen = Long.valueOf(req.getHeader(HttpHeaders.CONTENT_LENGTH));
        ServletFileUpload upload = new ServletFileUpload();
        ServletOutputStream servletOut = resp.getOutputStream();
            FileItemIterator itemIterator = upload.getItemIterator(req);
            while (itemIterator.hasNext()) {
                FileItemStream streamItem = itemIterator.next();
                if (streamItem.getFieldName().equals("ova")) {
                    String nameWithoutQuotas = streamItem.getName();
                    nameWithoutQuotas = nameWithoutQuotas.substring(0, nameWithoutQuotas.lastIndexOf('.'));
                    File tf = File.createTempFile("ova-rm", ".ova");
                    FileOutputStream fos = new FileOutputStream(tf);
                    copy(streamItem.openStream(), fos, servletOut, 1024 * 8, expLen);
                    fos.close();
                    try {
                        app.getBean(OVAImporter.class).importOVA(tf, nameWithoutQuotas, timeout, port);
                    } catch (Exception e) {
                        throw new ServletException(e);
                    }
                }
            }

        resp.setHeader("Transfer-Encoding", "chunked");
        byte timeout = parseTimeoutParameter(req);
        int port = parsePortParameter(req);
        long expLen = Long.valueOf(req.getHeader(HttpHeaders.CONTENT_LENGTH));
        ServletFileUpload upload = new ServletFileUpload();
        ServletOutputStream servletOut = resp.getOutputStream();
            FileItemIterator itemIterator = upload.getItemIterator(req);
            while (itemIterator.hasNext()) {
                FileItemStream streamItem = itemIterator.next();
                if (streamItem.getFieldName().equals("ova")) {
                    String nameWithoutQuotas = streamItem.getName();
                    nameWithoutQuotas = nameWithoutQuotas.substring(0, nameWithoutQuotas.lastIndexOf('.'));
                    File tf = File.createTempFile("ova-rm", ".ova");
                    FileOutputStream fos = new FileOutputStream(tf);
                    copy(streamItem.openStream(), fos, servletOut, 1024 * 8, expLen);
                    fos.close();
                    try {
                        app.getBean(OVAImporter.class).importOVA(tf, nameWithoutQuotas, timeout, port);
                    } catch (Exception e) {
                        throw new ServletException(e);
                    }
                }
            }

. Using the new version I have this constructor: new JakartaServletFileUpload<FileItem<I>, FileItemFactory<I>>();. How to use the constructor properly?

Live only exception with jaxb

Iv got an exception that I can not reproduce locally.

        java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 16

This is the writeMetadata method:

    try {
        Metadata md = prepareMetadata(o);
        md.setVersioning(new Versioning());
        TranslationStack stack = o.getStack();

        String currentProjectVersion = generateVersionNumber(o, stack);
        md.getVersioning().setLatest(currentProjectVersion);
        if (fin.isFinal(currentProjectVersion)) {
            md.getVersioning().setRelease(currentProjectVersion);
        }

        List<Version> versions = md.getVersioning().getVersions();
        Version e = new Version();
        e.setVersion(currentProjectVersion);
        versions.add(e);
        marshaller.getMetadataMarshaller().marshal(md, baos);
        return true;
    } catch (JAXBException ex) {
        LOG.log(Level.SEVERE, "Can not marshall!", ex);
        return false;
    }
}

private boolean writeMetadata(final TranslationMavenRelevation o, final ByteArrayOutputStream baos) {
    try {
        Metadata md = prepareMetadata(o);
        md.setVersioning(new Versioning());
        TranslationStack stack = o.getStack();

        String currentProjectVersion = generateVersionNumber(o, stack);
        md.getVersioning().setLatest(currentProjectVersion);
        if (fin.isFinal(currentProjectVersion)) {
            md.getVersioning().setRelease(currentProjectVersion);

        List<Version> versions = md.getVersioning().getVersions();
        Version e = new Version();
        e.setVersion(currentProjectVersion);
        versions.add(e);

HQL not working. Gives strange Exception in console.

How could that happen? I have this HQL:

SELECT mfr.id FROM EMailToEMailFolderOrdered mfr WHERE NOT(SIZE(mfr.EMail) = MAX(mfr.orderNumber) AND MIN(mfr.orderNumber)=1) GROUP BY mfr.id

HQL very slow

A HQL query I use is very slow.

SELECT
    CONCAT(t.javaType,
    'µ',
    t.systemName) as v,
    CASE
        WHEN SIZE(t.SQLDatabaseColumns) > 0 THEN CONCAT(t.systemName,
        ' (',
        SIZE(t.SQLDatabaseColumns),
        ')')
        ELSE t.systemName
    END as name
FROM
    SQLDatabaseType t
WHERE
    t.database.id = :db
ORDER BY
    SIZE(t.SQLDatabaseColumns) DESC,
    LENGTH(t.systemName) ASC,
    SUBSTR(t.systemName,
    1,
    1) DESC

SELECT
    CONCAT(t.javaType,
    'µ',
    t.systemName) as v,
    CASE
        WHEN SIZE(t.SQLDatabaseColumns) > 0 THEN CONCAT(t.systemName,
        ' (',
        SIZE(t.SQLDatabaseColumns),
        ')')
        ELSE t.systemName
    END as name
FROM
    SQLDatabaseType t
WHERE
    t.database.id = :db
ORDER BY
    SIZE(t.SQLDatabaseColumns) DESC,
    LENGTH(t.systemName) ASC,
    SUBSTR(t.systemName,
    1,
    1) DESC

What the query should do: The Query should output two columns: 1. Integerµint8 as a concat of the java-type, the letter 'µ' and then the database-native type. 2. int8 (29) what means that the type int8 is used 29 times. Ok, the reason why this query is slow is: SIZE(t.SQLDatabaseColumn) is executed multiple times. How to improve the speed in HQL?
