saxparser.parse(uri, handler) throws NPE on windows XP when the 'uri' is blank or non-existant


To reproduce the failure :
--------------------------
copy dom.jar xalan.jar & xercesImpl.jar from wspack1.5
nightly build promoted sept 22


setenv JAVA_HOME /home/sa122568/Jaxp/jdk1.4.2_04/win
setenv PATH .:$JAVA_HOME/bin:$PATH

setenv CLASSPATH .:./dom.jar:./xalan.jar:./xercesImpl.jar

Testcase attached - Test.java

javac Test.java
java Test

when the 'uri' is blank or non-existant
saxparser.parse(uri, handler);
should throw IOException

but throws NPE on windows XP
works properly on Solsparc

From the comment in the testcase it looks this was fixed earlier
"// GTM added this for WinXP platform which throws null ptr here"
