SoftReferenceSymbolTable: rehash() and removeEntry() incorrectly handles
SREntries
----------------------------------------------------------------------------------
Key: XERCESJ-1520
URL: https://issues.apache.org/jira/browse/XERCESJ-1520
Project: Xerces2-J
Issue Type: Bug
Components: Other
Affects Versions: 2.11.0
Reporter: Michael Glavassevich
While debugging I noticed that fCount can become negative if rehash()
encounters cleared SREntries. This occurs because we process the SREntries
again in removeEntry() without recognizing that they've already been removed
from the table. We also weren't correctly / consistently updating the 'next',
'prev' and 'bucket' fields in rehash() which can lead to the wrong entries
being removed from the table when we clean-up the reference queue.
