> Jitrino.OPT loops infinitely in inlineJSR() when an exception from a subroutine (JSR->RET) is expected
> To reproduce:
> * compile the attached hand-crafted Jasmin source ExcInFinallyTest.j:
> java -jar jasmin.jar ExcInFinallyTest.j
> * run on OPT:
> $HARMONY -Xem:opt ExcInFinallyTest
> you will get an infinite loop (in compilation). This test passes on Jitrino.JET and interpreter.
> If you rebuild Jitrino in debug mode, the following assertion would be caught:
> java: /export/users/evpasko/svn/3/trunk/working_vm/vm/jitrino/src/optimizer/FlowGraph.cpp:457: void Jitrino::findNodesInRegion(Jitrino::Node*, Jitrino::Node*, Jitrino::StlBitVector&): Assertion `!inEdges.empty()' failed.
> SIGABRT in VM code.
> Stack trace:
>         1: ?? (??:-1)
>         2: abort (??:-1)
>         3: __assert_fail (??:-1)
>         4: findNodesInRegion (/export/users/evpasko/svn/3/trunk/working_vm/vm/jitrino/src/optimizer/FlowGraph.cpp:458)

> [snip]
> obviously, the bug is in the subroutine inlining algorithm
