This will > cause refCount to -1 and isReadReference method was returning true > (refCount.get() != 0 This is causing store file not to be deleted. This may > also cause issue in situation when some thread is holding a scanner but it > may actually be closed due to above bug. Impact of this would be really high. > Attatching patch for the fix which makes sure if reference is held either > thru getScanner method or constructor, ref is always updated. Patch also > contains a test which validates the issue. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
