George Timoshenko commented on HARMONY-2259:
--------------------------------------------

Huh

it was really interesting.

this "magic" method:  "/$Proxy0::string" has 4 exception catchers and 2 exception handlers:

1 java/lang/Error                                  HANDLER_1
2 java/lang/RuntimeException          HANDLER_1
3 SubException                                    HANDLER_1
4 java/lang/Throwable                        HANDLER_2

HANDLER_1 - just rethrows an exception

HANDLER_2 creates UndeclaredThrowableException and throws it


the problem was that CodeSelector of Jitrino::OPT transformed this "picture" and in CG we had:

1.SubException                   HANDLER_1
2 java/lang/Throwable       HANDLER_2


The patch is being prepared
