             Summary: Unsynchronized HashMap.put leads to infinite loop
                 Key: COCOON-2362
                 URL: https://issues.apache.org/jira/browse/COCOON-2362
             Project: Cocoon
          Issue Type: Bug
          Components: * Cocoon Core
    Affects Versions: 2.1.12
            Reporter: Alfred Nathaniel
             Fix For: 2.1.13


Under load a Cocoon thread occasionally starts spinning at 100% in an infinite 
loop.  The reason is concurrent writing to a HashMap without proper 
synchronization.  The two stack traces are:

{noformat}
java.util.HashMap.put (HashMap.java:420)
org.apache.cocoon.components.language.generator.GeneratorSelector.select 
(GeneratorSelector.java:125)
{noformat}

{noformat}
java.util.HashMap.getEntry(HashMap.java:465)
java.util.HashMap.get(HashMap.java:417)
org.apache.cocoon.reading.ResourceReader.getLastModified(ResourceReader.java:242)
