The problem comes from a null scope.
+1 for RC2
Changed TypeVariableBinding#computeUniqueKey(...) to use the index of the method instead of its source position. Adpated BindingKeyResolver to this changed. Added regression test ASTConverter15Test#test0187() and changed BatchASTCreationTest#test065() to reflect this change.
Verified in N20050606-0010 + JDT/Core HEAD
Verified for 3.1 RC2 using build I20050610-0010
