[ https://issues.apache.org/jira/browse/OPENJPA-640?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adam Hardy updated OPENJPA-640:
-------------------------------
Affects Version/s: 1.2.0
> ClassNotFoundException for InstrumentationFactory upon startup
> --------------------------------------------------------------
>
> Key: OPENJPA-640
> URL: https://issues.apache.org/jira/browse/OPENJPA-640
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.0.2, 1.1.0, 1.2.0
> Environment: JDK6, 1.2.0-trunk
> Reporter: Ming Fai
> Priority: Minor
>
> This problem exists for a long time and it affects more than other people as well. Refer to an old thread in the mail list.
> http://mail-archives.apache.org/mod_mbox/openjpa-users/200801.mbox/%3C478963D8.209@gmail.com%3E
> java.lang.ClassNotFoundException: org.apache.openjpa.enhance.InstrumentationFactory
> at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
> at java.security.AccessController.doPrivileged(Native Method)
> at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
> at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
> at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:276)
> at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
> at sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:280)
> at sun.instrument.InstrumentationImpl.loadClassAndCallAgentmain(InstrumentationImpl.java:348)
> Previously, I had an old trick to patch the org.apache.openjpa.enhance.InstrumentationFactory.jar to include the InstrumentationFactory but it doesn't work now.
> Remarks: the problem is merely about displaying a piece of stacktrace but there is no actual impact to the OpenJPA function. (that's why I marked the priority as minor.)
