Rico Neubauer created JXPATH-178:
------------------------------------
Summary: Contention on functions can be reduced
Key: JXPATH-178
URL: https://issues.apache.org/jira/browse/JXPATH-178
Project: Commons JXPath
Issue Type: Improvement
Affects Versions: 1.3
Reporter: Rico Neubauer
Priority: Minor
Several series of thread dumps showed us that some avoidable synchronization in
jxpath causes plenty of blocked threads waiting on the sync block under heavy
load.
Using concurrent map makes the things better.
See this for a proposed fix:
