[jira] Commented: (OPENJPA-41) transforming classes doesn't work
[ http://issues.apache.org/jira/browse/OPENJPA-41?page=comments#action_12438591 ]
Marc Prud'hommeaux commented on OPENJPA-41:
-------------------------------------------
The problem seems to be coming from reentrant re-use of the same XMLMetaDataParser, which winds up calling reset() on the parser in the reentrant call, which messes it up when its continued use is attempted from the parent call. While this could be worked around by just using a new XMLMetaDataParser, the problem runs deeper: why is the reentrancy happening at all? Specifically, it looks like there is a reentrant construction of a PCEnhancer(), which probably shouldn't be happening.

> transforming classes doesn't work
> ---------------------------------
>
> Key: OPENJPA-41
> URL: http://issues.apache.org/jira/browse/OPENJPA-41
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Environment: WinXP, Tomcat 5.5.17, Spring 2.0-RC4
> Reporter: Costin Leau
> Assigned To: Marc Prud'hommeaux
> Attachments: petclinic.zip, spring-tomcat-weaver.jar, stacktrace.txt
>
>
> I've tried several versions of OpenJPA including the most recent one(svn 4409856) to run Spring's Petclinic with class level LoadTimeWeaver on OpenJPA.
> I have attached the stacktrace that I get. The same example works fine with Toplink.
> I have attached petclinic w/o some of the libs to gain space; basically add the OpenJPA libs and deploy the war into Tomcat. Note that you'll also have to place spring-tomcat-weaver.jar under Tomcat's server/lib (this should be enough - if you have problems let me know or take a look at the Spring reference documentation).
> When the webapp starts, the exception pops up.
