Adam Heath reopened OFBIZ-3779:
-------------------------------
Sorry, I had to revert this. It breaks the test cases. If you edit
framework/base/build.xml, so that only UtilCache is being tested, the
testChangeMemSize testcase fails with the new library. Reducing the capacity
of CLHM *must* remove items in LRU order. Any other removal order doesn't make
sense; If I reduce the capacity, I want to keep the items that were most
recently used, and throw away items that are older, until the size is within
the new limit.

>
> The UtilCache class should use v1.0 of the CLHM library. While the previous
> version is fully functional, I am no longer supporting it. The new design
> should be faster and more reliable due to not needing to use a pseudo LRU
> algorithm for performance (which has degradation scenarios ). A true LRU is
> now supported with no lock contention issues. Please consider upgrading when
> convenient.
