[infinispan-issues] [JBoss JIRA] (ISPN-1546) FineGrainedAtomicMap key and value iterators are not threadsafe
[
https://issues.jboss.org/browse/ISPN-1546?page=com.atlassian.jira.plugin....
]
Vladimir Blagojevic commented on ISPN-1546:
-------------------------------------------
Sanne, not sure how is this happening, lets figure it out! Some other thread must be
invoking write operations on the same AtomicHashMap i.e FastCopyHashMap delegate field of
AtomicHashMap since the thread that has been dumped above called
FineGrainedAtomicHashMapProxy.keySet?

Invoking #keySet() or #values() might fail, even when using a transaction to isolate
