-----------------------------------------------
Anil, the CCLA doesn't cover individual contributions though given how small
the patch is answering the questions is good enough here. In general we ask for
a signed ICLA [1] from everyone. Thanks.

> 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];
