This is a bug in gradle that we need to work around in the FX build.gradle script.

See https://github.com/gradle/gradle/issues/3849 for details.

On Linux and Mac this could fail if sym-links are used or it you have an extra "/" in your path, but a normal setup will not hit this problem on these platforms.

On Windows, this will fail always.

To reproduce this, do the following on Windows:

1. Download jdk-10-ea+36 (from java.net)

2. Unpack it and set your JAVA_HOME and PATH variables to point to it

3. Run 'gradle test'

It will fail with a message similar to:

    Could not determine Java version using executable C:/java/jdk-10//bin/java.exe.
