Hi,

While parsing a hotspot log (jitwatch is using zulu11.58.23-ca-jdk11.0.16.1-win_x64) jitwatch stopped with the following exception:

Exception in thread "Thread-3" java.lang.VerifyError: Cannot inherit from final class at java.base/java.lang.ClassLoader.defineClass1(Native Method) at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1017) at java.base/java.security.SecureClassLoader.defineClass(SecureClassLoader.java:174) at java.base/java.net.URLClassLoader.defineClass(URLClassLoader.java:555) at java.base/java.net.URLClassLoader$1.run(URLClassLoader.java:458) at java.base/java.net.URLClassLoader$1.run(URLClassLoader.java:452) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:451) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:589) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:398) at org.adoptopenjdk.jitwatch.util.ClassUtil.loadClassWithoutInitialising(ClassUtil.java:55) at org.adoptopenjdk.jitwatch.util.ParseUtil.lateLoadMetaClass(ParseUtil.java:1115) at org.adoptopenjdk.jitwatch.model.JITDataModel.findMetaMember(JITDataModel.java:257) at org.adoptopenjdk.jitwatch.util.ParseUtil.findMemberWithSignature(ParseUtil.java:352) at org.adoptopenjdk.jitwatch.parser.AbstractLogParser.findMemberWithSignature(AbstractLogParser.java:250) at org.adoptopenjdk.jitwatch.parser.AbstractLogParser.handleMember(AbstractLogParser.java:576) at org.adoptopenjdk.jitwatch.parser.AbstractLogParser.handleMethodLine(AbstractLogParser.java:479) at org.adoptopenjdk.jitwatch.parser.AbstractLogParser.handleTagQueued(AbstractLogParser.java:373) at org.adoptopenjdk.jitwatch.parser.hotspot.HotSpotLogParser.handleTag(HotSpotLogParser.java:356) at org.adoptopenjdk.jitwatch.parser.hotspot.HotSpotLogParser.parseLogCompilationLines(HotSpotLogParser.java:154) at org.adoptopenjdk.jitwatch.parser.hotspot.HotSpotLogParser.parseLogFile(HotSpotLogParser.java:130) at org.adoptopenjdk.jitwatch.parser.AbstractLogParser.processLogFile(AbstractLogParser.java:366) at org.adoptopenjdk.jitwatch.parser.ILogParser.processLogFile(ILogParser.java:23) at org.adoptopenjdk.jitwatch.ui.main.JITWatchUI$1.run(JITWatchUI.java:253) at java.base/java.lang.Thread.run(Thread.java:829)

I can't figure out how to go past this.

Thanks

The tool UI was started on windows as:

git clone https://github.com/AdoptOpenJDK/jitwatch.git
cd jitwatch
set java_home=C:\downloads\zulu11.58.23-ca-jdk11.0.16.1-win_x64\zulu11.58.23-ca-jdk11.0.16.1-win_x64
gradlew clean build run

The same exception is raised if the tool is run as : 'C:\downloads\zulu11.58.23-ca-jdk11.0.16.1-win_x64\zulu11.58.23-ca-jdk11.0.16.1-win_x64\bin\java -jar jitwatch-ui-1.4.7-shaded-win.jar'

The hotspot log that was loaded into the tools was produced by a java application running on linux in an OpenJDK Runtime Environment (Zulu 8.64.0.19-CA-linux64) (build 1.8.0_345-b01) JVM.

If I run jitwatch-ui-1.4.7-shaded-win.jar with java 17 as 'C:\downloads\zulu17.36.17-ca-jdk17.0.4.1-win_x64\zulu17.36.17-ca-jdk17.0.4.1-win_x64\bin\java -jar jitwatch-ui-1.4.7-shaded-win.jar' I get a different exception:
