NPE in to-spec when default language is XQuery
----------------------------------------------
Key: ODE-541
URL: https://issues.apache.org/jira/browse/ODE-541
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Affects Versions: 1.3
Reporter: Mark Ford
Priority: Minor
The expression language for the process has been set to
urn:oasis:names:tc:wsbpel:2.0:sublang:xquery1.0. The code below throws a NPE
because the xpath variable in the class is null. Looks like the subclass
OXQuery10ExpressionBPEL20 needs to override the getVariable method or perhaps
encapsulate access to the expression variable.
I suspect that the simple workaround is to override the expressionLanguage for
the to-spec to force XPath 1.0.
Caused by: java.lang.NullPointerException
