Project: Commons JCS
Issue Type: Bug
Components: Composite Cache

Using SVN version build Dec 20, 2012:
This code:
{code:java}
JCS<Long, String> jcs = JCS.getInstance("the region");
jcs.getGroupKeys("the group");
jcs.putInGroup(Long.valueOf(1), "the group", "some value");

actually something in the cache)
