Make sure embedded JRE takes precedence on OS X #32

From @rasband:

Another problem with the launcher on OS X is that I have not found a way to get it to use an embedded JRE. I tried putting a Java 8 JRE in Image.app/jre but the launcher did not use it.

If you launch ImageJ with the --debug flag, you can see that it is detecting the JRE, but still ultimately does not use it:

$ cd /Applications/Science/ImageJ.app
$ cp -rp /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre .
$ Contents/MacOS/ImageJ-macosx --debug
Available RAM: 4919MB, using 3/4 of that: 3690MB
JRE found in '/Applications/Science/ImageJ.app/jre'

Note that this needs to be retested with the latest ImageJ launcher which upgrades the OS X Java version detection.

I believe this was resolved in the 6.0.0 release
