[infinispan-issues] [JBoss JIRA] Commented: (ISPN-711) TimeoutException when explictly locking mutiple keys repeatedly

[Manik Surtani (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558407#action_12558407 ] 

Manik Surtani commented on ISPN-711:
------------------------------------

I've analysed this some more - you don't need a loop to cause this to fail.  In fact you don't even need multiple keys.  Here is a unit test that is much simpler, and depicts the same.

Interestingly, the issue may be somewhat artificial.  It is because the transaction doesn't contain any updates - and as an optimisation, the commit isn't broadcast.  

Note that un-commenting the put() in the test causes the test to pass.
