Ivan Lagunov created COCOON-2340: ------------------------------------ Summary: 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
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)
