------------------------------------------

What do you mean, Mikhail?

Sure, the line numbers for RI and Interpreter are the same, but the line numbers for JIT are different, and that is the problem.

> When JIT is enabled and exception is thrown in some method, the line number for the exception in incorrect: in some cases, it points not to the line where
> exception has occured, but to the first line of that method.
> The code to reproduce is attached, here's the output. Note the line numbers for RI and DRLVM interpreter (11, 23, 35) and DRLVM JIT (11, 19, 31).
> RI:
> C:\> java LineNumberTest
> Exception in thread "main" java.lang.RuntimeException
>         at LineNumberTest.check2(LineNumberTest.java:11)
>         at LineNumberTest.check1(LineNumberTest.java:23)
>         at LineNumberTest.main(LineNumberTest.java:35)
> DRLVM:
> C:\> java -Xint LineNumberTest
> Uncaught exception in main:
> java.lang.RuntimeException
>         at LineNumberTest.check2(LineNumberTest.java:11)
>         at LineNumberTest.check1(LineNumberTest.java:23)
