[infinispan-issues] [JBoss JIRA] Assigned: (ISPN-259) Concurrent puts fail with writeSkew

Concurrent puts fail with writeSkew ----------------------------------- Key: ISPN-259 URL: https://jira.jboss.org/jira/browse/ISPN-259 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency Affects Versions: 4.0.0.CR1 Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.0.0.CR2 Similar problem to JBCACHE-1555 is present in Infinispan: WriteSkew is detected even if we haven't read any data previously in the transaction. The root cause could be the same as in JBCACHE-1555 but haven't looked into it further yet. java.util.concurrent.ExecutionException: org.infinispan.CacheException: Detected write skew on key [k]. Another process has changed the entry since we last read it! at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:252) at java.util.concurrent.FutureTask.get(FutureTask.java:111) at org.infinispan.api.mvcc.repeatable_read.WriteSkewTest.testWriteSkewWithOnlyPut(WriteSkewTest.java:121) Caused by: org.infinispan.CacheException: Detected write skew on key [k].
