[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....
]
Sanne Grinovero commented on ISPN-1546:
---------------------------------------
@Manik as you can see from the stack, the issue happens while trying to make a defensive
copy; I can't make one nor iterate on it as another thread might be applying
modifications and that's out of my control (unless I acquire a pessimistic lock on the
whole thing again.. ).
