@Aleksey, when I try to configure openjdk8 with that option I get an error:
configure: error: unrecognized options: --with-native-debug-symbols
Exactly, I I downloaded jdk8u and I
I don't think I had any issues with symbol resolution and stack unwinding
with the default fastdebug build (provided that the frame pointers are
preserved).
Can anyone shed some light on what the benefits of
--with-native-debug-symbols=internal are?
