[infinispan-issues] [JBoss JIRA] (ISPN-1822) Cache entry not evicted from memory on IBM JDK when another entry was loaded from a cache loader and maxEntries had been reached

[ https://issues.jboss.org/browse/ISPN-1822?page=com.atlassian.jira.plugin.... ] Martin Gencur edited comment on ISPN-1822 at 9/14/12 8:20 AM: -------------------------------------------------------------- Hmm, it seems that setting lower max entries limit on IBM JDK does not help. I did the following change in BoundedConcurrentHashMap but the number of entries in the cache was still exceeded during the test: {code:java} int previousPowerOfTwo = 0; //new line while (cap < c) { previousPowerOfTwo = cap; //new line cap <<= 1; } ... for (int i = 0; i < this.segments.length; ++i) { this.segments[i] = new Segment<K, V>(cap, previousPowerOfTwo /*changed param*/, DEFAULT_LOAD_FACTOR, evictionStrategy, evictionListener); } {code} The cap parameter sets the size of a segment and previousPowerOfTwo sets the limit when eviction should be executed. The previousPowerOfTwo is always lower and what was there previously but setting this limit to a lower number does not help. There are still more entries in the cache that should be. was (Author: mgencur): Hmm, it seems that setting lower max entries limit on IBM JDK does not help.
