Can't start Eclipse - Java was started but returned exit code=13 !!! SOLVED

I got this error, and found that my PATH variable (on Windows) was probably changed. First in my PATH was this entry:

C:\ProgramData\Oracle\Java\javapath

..and eclipse ran "C:\ProgramData\Oracle\Java\javapath\javaw" - which gave the error. I suspect that this is something that came along with an installation of Java 8.

I have several java versions installed (6,7 and 8), so I removed that entry from the PATH and tried to restart Eclipse again, which worked fine.
