Want to upgrade Roller to OpenJPA 1.0 but locks up
I'm trying to upgrade the Roller 4.0 code base from OpenJPA 0.9.7 to
OpenJPA 1.0 but I'm running into a blocking issue.
The <openjpac> task that we use to enhance our POJOs is locking up
during the build process. There are no error messages or stack traces,
but the CPU goes to about 98% (on my core duo MacBook pro) and Ant
just hangs.
Any hints on how I could debug this problem?

Just a follow up, using the latest 1.0.1-SNAPSHOT solved this problem
Thanks again, Dave

Note that this problem would not have occurred if you were running the
OpenJPA enhancer on your types. Since you're (presumably) shipping the
classes in your product, you might want to consider using the
enhancer; it will deliver some performance and memory optimizations
vs. running without the enhancer.

That must be it. Roller is guilty of "logic in getters for entities
with property access". I'll grab a 1.0.1 snapshot and try it out.
Thanks for the help.

Hi,
I think that this is OPENJPA-335 [1]. I just checked in a fix to 1.0.x
that works against your use case. It'll be available in the 1.0.1 and
1.1.0 snapshots in a few hours.

Well, it doesn't look like it's in a deadlock or anything.... can you
take another couple of thread dumps after a couple of seconds and send
them along so we can see what's going on? Also, what output do you get
when running with the SQL log channel set to TRACE? (openjpa.Log
property set to 'SQL=TRACE')

Hi,
Can you post a thread dump? I think you can get one by hitting
control-shift-|, although I always end up hitting two or three things
before getting it.
