Manik Surtani commented on ISPN-863:
------------------------------------

@Mircea while that is another metric with which to trigger eviction, it doesn't tell you if your JVM is close to running out of memory.  E.g., it doesn't record memory used by Infinispan outside of the container, as well as any other application or framework code.  @Dave's approach triggers eviction based on a percentage threshold of JVM memory used.  It's just another approach.

> Allow user to specify percentage threshold upon which eviction will kick in and begin evicting entries based on the specified strategy. This would allow user to create a cache that will attempt to keep as many entries in memory as possible without having to specify maxEntries.
