Mikhail Fursov commented on HARMONY-3738:
-----------------------------------------

I've prepared a fix for this issue but I do not know how to write regression test here: it depends on vmmagic.jar in javac classpath.
Does anyone knows how to modify javac's classpath for regression tests?

> I tried to improve GCMap checking capabilities for managed<-> unmanaged pointers conversion and found that this simple test fails when run with Jitrino.OPT.
> I8Lowerer is not able to process pattern produced by this test.
> This bug is not critical and does not affect any scenarios I know.

> import org.vmmagic.unboxed.*;

>     static long val;
>     public static void main(String[] args) {
>         a = Address.fromLong(1L);
>         val = a.toLong();
>     }
