Problem with jikes & EJB

Question

I've been experiencing a problem using jikes to compile EJBs. Has anyone
has this type of problem and is there a known fix?
The beans seem to compile fine, but I get an error when trying to deploy
them. Here's the error:
weblogic.ejb.common.DeploymentException: Unexpected I/O exception during
deployment:
weblogic.ejb.common.DeploymentException: Problem deploying a bean:
java.lang.VerifyError: (class:
com/criatech/contractstation/party/provider/PartyManagerBeanEOImpl_ServiceSt
ub, method: ensureInitialized signature: ()V) Illegal target of jump or
branch
at java.lang.Class.getConstructor0(Native Method)
at java.lang.Class.getConstructor(Class.java:886)
Thoughts?

That seems to be the problem. It only happens on one bean which is a very
large one. It appears to work ok with the javac 1.3 compiler, but no luck
with jikes. It's unfortunate, because jikes is SO much faster.
At least I know someone else is seeing this problem. Thanks for the info.

Hi.
This sounds a bit like a problem we were having when compiling one of the
generated classes for a bean with a huge number of methods (~400). The
ensureInitialised method (I think, it might be a different method now -the
name of the class changes in every WLS version) got so big that some ofthe
jump instructions needed to become wide jump instructions but both javacand
jikes got it wrong.
For us, the workaround was (and still is) to use kjc(http://www.dms.at/kopi/)
to compile the generated classes.
This may or may not be your problem, however.
Toby.
