Subject [jira] Commented: (HARMONY-3079) [dlrvm][classloader][opt] Opt does not handle exception raised by classloader (assertion fails classloader.cpp:1521)

Alexey Varlamov commented on HARMONY-3079:
------------------------------------------

Gregory, please hold on resolving/closing this issue - the patch you have applied is just
a workaround; while it may help to make some progress with EUT, still more solid solution
is needed (on JIT side, looking forward to lazy resolution).

> Assertion failed - classloader.cpp:1521 on EUT jdtdebug suit. 
> Testcase:2 methods return the same type, 1-st method calls the 2-nd:
> class A;
> class B{
> static A getA(){return new A();}}
> class C{
> static A getA(){return B.getA();}}
> main: C.getA();
> JIT tries to resolve A class 2 times. If class is not accessable, classloader raises
ClassNotfoundException 1-st time, JIT does not handle it, then when the 2-nd time JIT tries
to resolve the same class VM fails with the assert on loading (because exception was already
raised). 
> The issue here is that  JIT does not handle raised exception by classloader in 1 compilation
session.
