opnejdk8 with jamvm linker error

[Martijn Verburg]

Hi Rizwan,

Welcome to OpenJDK.  The discuss list is for low volume discussion about
the OpenJDK community, governance etc.

I think your issue needs to be reported over at JamVM -
https://sourceforge.net/p/jamvm/mailman/jamvm-general/

Cheers,
Martijn
