ClassLoader exception when running ant on windows with java 1.8

问题

I ran into this issue when running ant on a windows system with java 1.8.60. This was working fine when running java 1.7.25. Even more interesting : it runs fine when executed on a mac?

I am kind of lost since there is not much pointing me towards a cause of this problem.

Error occurred during initialization of VM

Sure the JVM was installed properly? We had the same problem when the JVM was installed via a repository (CVS) which converted some text-files from/to DOS/UNIX format.
