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

[DM Klerk]

Dont you wish everything in life could be that simple!
The crashes I described earlier disappeared when I moved from jdk7 to jdk8,
as Tom says all you need to do is point eclipse to use jre8 as runtime for
your application and everything works like a charm, thank you Kevin and
Jonh for your swift replies.
