what does java -version return ?

I bet you it says java 8 64.

And your java 7 says java 32.

And that worked on Luna because switchyard seem to not use the standard
target platform but instead have just this:

https://github.com/jboss-switchyard/tools/blob/master/eclipse/pom.xml#L194
x86

where it should be having also x86_64:
https://github.com/jbosstools/jbosstools-build/blob/master/parent/pom.xml#L166

so in short: I don't think SY ever was build and tested against 64 bit 
windows before now ;)

solution: either make SY build with a proper target platform or use java 
32 bit to build it.

long term I would prefer it uses proper target platform.
