------------------------------------------------------------
Key: TUSCANY-1043
URL: https://issues.apache.org/jira/browse/TUSCANY-1043
Project: Tuscany
Issue Type: Bug
Components: Java SCA Core, Java SCA Integration Tests
Reporter: Lou Amodeo
r494421 - NullPointerException is thrown by PassByValueInterceptor when
processing the 2 nd of 3 callbacks. A multiple callbacks issue was fixed in
JIRA-976 and this integration testcase was functioning. This issue that is
now occurring appears to be completely different than -976. Please see the
testcase attached to -976 to reproduce.
