"Console Process execution FAIL: UnsupportedClassVersionError" To view the discussion, visit: http://community.jboss.org/message/559915#559915 -------------------------------------------------------------- JBPM 4.4 with JDK 1.5.8 Process built with Ant in Eclipse, where everybody is using the same JDK as JBoss. After deploying a very simple process, the process is executed in the BPM Console by selecting 'Start' in the Process Overview. It fails with this error: UnsupportedClassVersionError: Bad version number in .class file at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at java.lang.ClassLoader.defineClass(ClassLoader.java:465) at org.jbpm.pvm.internal.repository.DeploymentClassLoader.findClass(DeploymentClassLoader.java:113) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:242) at org.jbpm.pvm.internal.util.ReflectUtil.classForName(ReflectUtil.java:434) at org.jbpm.pvm.internal.wire.descriptor.ObjectDescriptor.construct(ObjectDescriptor.java:141) at org.jbpm.pvm.internal.wire.WireContext.construct(WireContext.java:487) at org.jbpm.pvm.internal.wire.WireContext.create(WireContext.java:466) at org.jbpm.pvm.internal.wire.WireContext.create(WireContext.java:264) at org.jbpm.pvm.internal.util.ReflectUtil.instantiateUserCode(ReflectUtil.java:414) at org.jbpm.pvm.internal.wire.usercode.UserCodeReference.getObject(UserCodeReference.java:63) at org.jbpm.pvm.internal.wire.usercode.UserCodeReference.getObject(UserCodeReference.java:47) at org.jbpm.jpdl.internal.activity.JavaActivity.perform(JavaActivity.java:58) at org.jbpm.jpdl.internal.activity.JpdlAutomaticActivity.execute(JpdlAutomaticActivity.java:15) This is usually because the Java version the byte code was compiled with is different than what is being used to run it with. I know this, but cannot understand how it can be the case, as I've described above, the Java versions are made sure to be the same. Or at least, that's what I claim.. Any clues where I might have gone off the path would be appreciated..
