Bug RT-24142 crashes the VM when you touch a JSObject

[DM Klerk]

My application is an eclipse RCP app (swt, jface, jdt, jsdt and more),
which uses Tom's efxclipse for osgi integration.
According to eclipse's bug tracker jdk8 is not fully supported yet.
Is it at this time even possible to use jdk8 for this or must i wait for
either: a. eclipse supporting jdk8 or b. oracle releasing a jdk7 update
with my bug fixed? And if b is the case, does anyone know when to expect
such a release?
