[JBoss JIRA] (ISPN-4182) ClusteredCacheWithAsyncDirTest does not properly ensure each db url is unique for parallel tests
by Adrian Nistor (JIRA)
[ https://issues.jboss.org/browse/ISPN-4182?page=com.atlassian.jira.plugin.... ]
Adrian Nistor commented on ISPN-4182:
-------------------------------------
To be more specific, the collisions occur if a previous test did not succeed in stopping the cache store correctly and dropping the table. The next test will fail to create the table because it exists already. So we need to ensure db instances are unique for nodes of the same test cluster and also unique compared to the ones used by next test - thus global uniqueness is required.

> The test should ensure the db url is not the same across nodes of all parallel tests because they all run in the same jvm and the H2 instances might collide.

> Sometimes when I start one server in a cluster I see the NullPointerException reproduced below. This only occurs if there is another server running. I run multiple caches with clustering using invalidation. JGroups using JDBC_PING and TCP. The caches are non-transactional.
> The NPE is because the keyEq (Equivalence instance for keys) is null. I believe this is because the command is processed before the start() method has been called on the AbstractInvocationContextFactory, as the start() method sets the keyEq ivar.
> At this point I'm not sure how to fix it!
