I get this error:
java.lang.InternalError: name is too long to represent at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at weblogic.utils.classloaders.GenericClassLoader.defineClass(GenericClassLoader.java:338) at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(GenericClassLoader.java:291) at weblogic.utils.classloaders.GenericClassLoader.findClass(GenericClassLoader.java:259)
Which seems related to some debug functionality (in fact removing
-Xdebug command line option the error disappears). I've also found some information in ASF Bugzilla. Is there a way to solve this?
Possible solutions I can think of are to change the JVM (using JRockit which should't have this issue), but I do not really know if this can solve the issue and if it can break something else.
update The bug mentioned in the original answer below has now been closed!
As noted in the article that you reference, this is a bug in the Sun/Oracle JVM implementation. At the time of writing, it is unresolved.
I can think of three ways to work around the issue:
- Don't generate SMAP files at all (eg: don't run with -Xdebug or use suppressSmap-like settings)
- Try to make sure that the size of the debug information is small (eg: reduce the size of your code)
- Use a different virtual machine implementation.
