Help needed updating java/eclipse to 4.11

[Jonathan Chen]

Hi,

With the impending demise of java/eclipse 4.6 due to webkit-gtk2
deprecation, I've been attempting to update the port to
eclipse-4.11.RC2. Progress has been good, and I've managed to produce
an executable from the build. Unfortunately, while I get a
splashscreen displayed, the application currently dies with:

java.lang.UnsatisfiedLinkError: org.eclipse.swt.internal.C.memmove(I[II)V

There's some issue with JNI bindings that I just don't understand, and
I'm hoping that some on the list (java@ or eclipse@) may be willing to
give me a hand. Please drop me a line if you're interested in helping
me bring java/eclipse up to date on FreeBSD.

Thanks!
