Javier Puerto reassigned COCOON-2340: ------------------------------------- Assignee: Javier Puerto > XMLByteStreamCompiler in not thread-safe > ---------------------------------------- > > Key: COCOON-2340 > URL: https://issues.apache.org/jira/browse/COCOON-2340 > Project: Cocoon > Issue Type: Bug > Components: * Cocoon Core > Affects Versions: 2.2 > Reporter: Ivan Lagunov > Assignee: Javier Puerto > > 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
