Ciaran Jessup updated ODE-574:
------------------------------
Attachment: StyleSheetCache.patch
This patch should now allow any OProcess instances that happen to be left in
memory due to 'belonging' to a cached Stylesheet to be garbage collected when
the process that contained the stylesheet is un-deployed. The patch definately
needs reviewing as the with/without slash code I put in seems un-neccessary but
I couldn't understand why the multi-key had a terminating slash when the
path-to-package wasn't constructed with one wherever I looked ;)
> Memory leak when Un-deploying processes that contain XSL stylesheets
> --------------------------------------------------------------------

> Key: ODE-574
> URL: https://issues.apache.org/jira/browse/ODE-574
> Project: ODE
> Issue Type: Bug
> Components: BPEL Compilation/Parsing, BPEL Runtime
> Environment: N/A
> Reporter: Ciaran Jessup
> Attachments: StyleSheetCache.patch

>
> Currently if the BPEL process contains any XSL stylesheets it will not free
> up *all* the memory that was allocated during the compilation/dehydration of
> the process. This seems to be because there is a cache of XSLTemplates
> stored in the XSLTransformHandler, and these XSLTemplates can sometimes
> contain (transitive) references back to the OProcess object instances (via
> for example the URIResolvers/XPAth Expressions). Unfortunately this cache
> lives forever (crucially even after the process has been un-deployed)
> because of this the object graph hanging from the OProcess object instance is
> never available for the GC to pick-off.
> There is also another reference issue in the ErrorListener that is associated
> with the XSLTransformHandler instance, but I don't really understand that bit
> of code just as yet, a patch for the former issue follows, I'm reviewing the
> ErrorListener issue currently.
