JCS has inconsistent locking of shared data
-------------------------------------------
Key: JCS-21
URL: https://issues.apache.org/jira/browse/JCS-21
Project: JCS
Issue Type: Bug
Affects Versions: jcs-1.2.7.9.2
Reporter: Michael Stevens
Assigned To: Aaron Smuts
Attachments: locking.diff
I've been looking at the trunk JCS code with findbugs (http://findbugs.sf.net/).
One of the things it does is warn when data is inconsistently synchronized - ie
when it is sometimes referenced inside a synchronized block and sometimes not.
This is not threadsafe - one thread may read old or inconsistent data.
I've patched all the places findbugs complains about by adding appropriate
synchronized() blocks.
I suspect this change may require some discussion :)
