Intermittent NPE from XRTreeFrag in ParameterTest(18)reused
Summary: Intermittent NPE from XRTreeFrag in
ParameterTest(18)reused
Product: XalanJ2
Version: CurrentCVS
Platform: PC
OS/Version: Windows NT/2K
Status: NEW
Severity: Normal
Priority: Other
Component: org.apache.xpath
AssignedTo: xalan-dev@xml.apache.org
ReportedBy: curcuru@apache.org
TestID: ParameterTest.java testCase3 r1.2
This test will intermittently throw an NPE when re-using an existing
transformer that has parameters set. Only happens 1 out of 3 or so runs of the
test; note that it does not fail, but does print out a HACK warning.
Traceback is:

Happens randomly on one of the many times the same transformer is re-used with
new parameters.
