Local fix
-Xjit:disableRedundantGotoElimination
Problem summary
An optimization called Redundant Goto Elimination (RGE) improperly handled a case in which a conditional branch instruction targeted its own fall-through path. An example might look like this: if (someCondition) { /* nothing in here */ } ...except that the optimizer usually deletes this kind of code quite aggressively and RGE never sees it. In the failing case, an unlikely series of events led the optimizer to produce this kind of code as an intermediate form in the midst of the optimization process. RGE then proceeded to process and transform this code incorrectly.
Problem conclusion
This APAR will be fixed in the following Java Releases: 7 SR8 (7.0.8.0) 7 R1 SR2 FP2 (7.1.2.2) 6 SR17 (6.0.17.0) 6 R1 SR9 (6.1.9.0) . The Redundant Goto Elimination optimization was fixed to leave this kind of code pattern alone. (Another subsequent optimization will process it properly.)
