Comment 1 Olivier Thomann CLA 2004-11-29 12:12:40 EST 
Jérôme,

It is possible that the compilationUnitResolver on DefaultBindingResolver is null.
To reproduce add this line at the end of test0081 in ASTConverter15Test.
assertFalse("Doesn't override itself", methodBinding.overrides(methodBinding));
Comment 2 Jerome Lanneluc CLA 2004-11-29 16:48:22 EST 
Changed DefaultBindingResolver to store the lookup environment instead of the
CompilationUnitResolver.
Added regression test CompatibilityRulesTests#test022()
Comment 3 Frederic Fusier CLA 2004-12-15 06:11:00 EST 
Verified for 3.1 M4 using build I200412142000 + ASTView 1.0.2.
