Subject [jira] [Commented] (COCOON-2340) XMLByteStreamCompiler in not thread-safe

Ivan Lagunov commented on COCOON-2340:
--------------------------------------

Hi Javier,

I would like to try Cocoon 2.2.1 first but could you say where it's located? I suppose it
must be under trunk here http://svn.apache.org/repos/asf/cocoon/trunk/ ? Is it stable enough
for Production usage? I mean it's written here that SNAPSHOTS are not tested and not guaranteed
to even build cleanly: https://cocoon.apache.org/mirror.cgi

>                 URL: https://issues.apache.org/jira/browse/COCOON-2340
>             Project: Cocoon
>          Issue Type: Bug
>          Components: * Cocoon Core
>    Affects Versions: 2.2
>            Reporter: Ivan Lagunov
>
> I'm periodically getting the following exceptions in different places:
> Caused by: java.lang.ArrayIndexOutOfBoundsException
>         at java.lang.System.arraycopy(Native Method)
>         at org.apache.cocoon.components.sax.XMLByteStreamCompiler.getSAXFragment(XMLByteStreamCompiler.java:61)
>         at org.apache.cocoon.components.pipeline.impl.ExpiresCachingProcessingPipeline.processXMLPipeline(ExpiresCachingProcessingPipeline.java:152)
> After debugging I've found the root cause. It happens due to multi-threading when one
thread allocates newbuf array, then another thread increments bufCount in write method and
then the first thread fails on System.arraycopy invocation.
> I suggest making getSAXFragment and write methods synchronized. It should resolve the
issue. If it helps, I'll provide a patch later.
