Preload sets the versions to null (repeatable read + write skew) ---------------------------------------------------------------- Key: ISPN-1990 URL: https://issues.jboss.org/browse/ISPN-1990 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 5.1.3.FINAL Environment: Java 6 (64bits) Infinispan 5.2.0-SNAPSHOT MacOS Reporter: Pedro Ruivo Assignee: Galder Zamarreño Labels: preload, skew, versioning, write Fix For: 5.3.0.Alpha1, 5.3.0.Final I think I've spotted a issue when I use repeatable read with write skew check and I preload the cache. I've made a test case to reproduce the bug. It can be found here [1]. The problem is that each keys preloaded is put in the container with version = null. When I try to commit a transaction, I get this exception: {code} java.lang.IllegalStateException: Entries cannot have null versions! at org.infinispan.container.entries.ClusteredRepeatableReadEntry.performWriteSkewCheck(ClusteredRepeatableReadEntry.java:44) at org.infinispan.transaction.WriteSkewHelper.performWriteSkewCheckAndReturnNewVersions(WriteSkewHelper.java:81) at org.infinispan.interceptors.locking.ClusteringDependentLogic$AllNodesLogic.createNewVersionsAndCheckForWriteSkews(ClusteringDependentLogic.java:133) at org.infinispan.interceptors.VersionedEntryWrappingInterceptor.visitPrepareCommand(VersionedEntryWrappingInterceptor.java:64) {code} I think that all info is in the test case, but if you need something let me know.
