> Key: XERCESJ-1423
> URL: https://issues.apache.org/jira/browse/XERCESJ-1423
> Project: Xerces2-J
> Issue Type: Bug
> Affects Versions: 2.9.1
> Environment: Windows XP SP3, and Arch Linux (2.6.31-ARCH)
> Reporter: Joe Baysdon
> Attachments: XERCESJ-1423.patch
>
> Original Estimate: 2h
> Remaining Estimate: 2h

> The rehash( ) method, in org.apache.xerces.util.SoftReferenceSymbolTable,
> does not re-set the SREntry.prev pointer to null, so the final entry placed
> in each bucket may have an improper "prev" value following the rehash( ).
> Since the removeEntry method uses that "prev" pointer to reconnect the linked
> list around the removed link, the linked list can contain an illegal cycle.
> These cycles may produce infinite loops in either of the addSymbol methods or
> in the rehash method, itself.
> The solution is to this line:
> e.prev = null;
> to the rehash method, following this line:
> e.next = newTable[index];
