Reset problem with ErrorHandlers
Summary: Reset problem with ErrorHandlers
Product: Xerces2-J
Version: 2.6.2
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: Other
Component: XML Schema Structures
AssignedTo: xerces-j-dev@xml.apache.org
ReportedBy: nnissar@ca.ibm.com
A Null Pointer Exception is encountered as a result of attempting to set a
feature in a hashtable to null in XSDHandler class.
>From Neil Delima:
XMLErrorHandler currErrorHandler = fErrorReporter.getErrorHandler();
if (currErrorHandler != fSchemaParser.getProperty +(ERROR_HANDLER)) {
fSchemaParser.setProperty(ERROR_HANDLER, currErrorHandler);
}
So if for the same parser:
Parse 1: If Error_Handler = "myErrHandler"
reset {
=>currErrorHandler = "myErrHandler"
=>fSchemaParser.getProperty(ERROR_HANDLER) = null
=>Enter if and fSchemaParser.getProperty(ERROR_HANDLER)
= "myErrHandler"
}
Parse 2: If Error_Handler = null
reset {
=>currErrorHandler = null
=>fSchemaParser.getProperty(ERROR_HANDLER) = "myErrHandler"
=>Enter if and set the property (in the hastable) to null
}
Hence the NPE. Adding currErrorHandler!=null in the check fixes the bug.
