> 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."
