New Revision: 985518
URL: http://svn.apache.org/viewvc?rev=985518&view=rev
Log:
Fixing JIRA Issue #1464: http://issues.apache.org/jira/browse/XERCESJ-1464. Use 31 bits in computing the hash instead of 27. Should improve the distribution symbols in a very large table. Thanks to Roland Illig for spotting this issue.
