> 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)
> {noformat}
