When trying to launch using a Unix JRE on OSX go-java-launcher fails with the following error:

panic: exec format error

goroutine 1 [running]:
panic(0x166760, 0xc8200baa50)
	/usr/local/go/src/runtime/panic.go:481 +0x3e6

main.main()

Very hard to debug. Would be nice to fail with a much easier to understand error.

Not really sure what to do here; suggestions?

No bright ideas unfortunately - at the very least I thought this might help if someone hits this error in future.
