Cache entry not evicted from memory on IBM JDK when another entry was loaded from a cache loader and maxEntries had been reached -------------------------------------------------------------------------------------------------------------------------------- Key: ISPN-1822 URL: https://issues.jboss.org/browse/ISPN-1822 Project: Infinispan Issue Type: Bug Components: Eviction Affects Versions: 5.1.0.FINAL Environment: java version "1.6.0" Java(TM) SE Runtime Environment (build pxi3260sr9fp1-20110208_03(SR9 FP1)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260sr9-20110203_74623 (JIT enabled, AOT enabled) ; java version "1.7.0" Java(TM) SE Runtime Environment (build pxi3270-20110827_01) IBM J9 VM (build 2.6, JRE 1.7.0 Linux x86-32 20110810_88604 (JIT enabled, AOT enabled) Reporter: Martin Gencur Assignee: Tristan Tarrant This behavior is specific to IBM JDK (I tried JDK6 and 7), it works fine with Java HotSpot. Steps to reproduce the problem: 1) set maxEntries for eviction to 2 and algorithm e.g. to LRU 2) store 3 entries key1, key2, key3 to the cache (after that you can see that the cache contains only 2 entries - key2 and key3, the first one was evicted from memory) 3) call cache.get("key1") 4) PROBLEM - cache contains all key1, key2, key3 even though it should contain only 2 entries - only happens with IBM JDK (6 or 7 ..no matter) I'll shortly issue a pull request with a test to ispn-core
