Yesterday Java 8 was officially released. When I try to compile and run my tests and application that use OpenJPA 2.3.0 with Java 8 I get errors (see below) when I try to enhance the entities or use the java agent. Are there plans to support Java 8 in the near future?
I did find the following issue which was unfortunately last updated almost half a year ago: https://issues.apache.org/jira/browse/OPENJPA-2386 Regards, Henno Vermeulen Java agent: 431 olgaPersistenceUnit WARN [main] openjpa.Enhance - An exception was thrown while attempting to perform class file transformation on "nl/hm/olga/core/entity/AbstractEntity":java.lang.IllegalArgumentException at org.apache.xbean.asm4.ClassReader.<init>(Unknown Source) at org.apache.xbean.asm4.ClassReader.<init>(Unknown Source) at org.apache.xbean.asm4.ClassReader.<init>(Unknown Source) at org.apache.openjpa.enhance.AsmAdaptor.toJava7ByteArray(AsmAdaptor.java:93) at org.apache.openjpa.enhance.AsmAdaptor.toByteArray(AsmAdaptor.java:78) at org.apache.openjpa.enhance.PCClassFileTransformer.transform0(PCClassFileTransformer.java:156) at org.apache.openjpa.enhance.PCClassFileTransformer.transform(PCClassFileTransformer.java:126) at sun.instrument.TransformerManager.transform(TransformerManager.java:188) at sun.instrument.InstrumentationImpl.transform(InstrumentationImpl.java:428) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:760) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:455) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:367) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:360) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:760) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:455) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:367) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:360) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at nl.hm.oblomow.application.server.OblomowServerStarter.main(OblomowServerStarter.java:32) Enhancer (through Maven plugin) ....
