Null pointer exception while doing wsdl get using useOriginalWsdl option.
Reason : underlying definitiion is not threadsafe
---------------------------------------------------------------------------------------------------------------------------
Key: AXIS2-3276
URL: https://issues.apache.org/jira/browse/AXIS2-3276
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: wsdl
Affects Versions: 1.2
Environment: HP UX
Reporter: Haneef Ali
Priority: Critical
I'm seeing Nullpointer exception during wsdl fetch. My webservice is created
using "useOriginalWSDL=true" option.
This happens only during concurrent access. It can be easily reproduced by
creating a JMeter test for http get with 5 thread. BTW I'm using Axis 1.2
From google search the reason for this seems to be
" This is because the WSDL handling system reuses javax.wsdl.Definition objects
across threads, which are not thread safe, because they internally use DOM
elements."
