QueryParser not handling TokenMgrError

           Summary: QueryParser not handling TokenMgrError
           Product: Lucene
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: QueryParser
        AssignedTo: lucene-dev@jakarta.apache.org
        ReportedBy: dcalvo@task.com.br


Hi,

With lucene-1.2-rc3, when a perform a search for "*", a TokenMgrError is thrown 
(see below). As a workaround, I started catching 
org.apache.lucene.queryParser.TokenMgrError in my application but I believe the 
correct solution is to change QueryParser.jj to start catching TokenMgrError 
and throwing a ParseException instead (just don't know the best place to do 
it ;-)

Best regards,

--Daniel
