devel/jdk/1.8: cannot use debugger

Hi,

I attempted to debug a Java application. However, as is shown below,
debugging does not work currently (presumably since the jdk was updated
recently). I found a FreeBSD bug report which reports the same
problem [1]. They fixed the problem with a patch [2]. I have not tried
the patch yet but I assume it would fix the problem for OpenBSD as well.
I'm not sending a diff since I'm not sure you can use it, given the
whole CLA thing.

Thanks,
Caspar Schutijser
