[#323] exec arguments missing

[bmarwell]

fixes #323

Can only reproduce in IT, not in unit test. Fix is WIP

[bmarwell]

proposed fix:

    private boolean isLongClassPathArgument( String arg )
    {
        return executable.endsWith("java") && longClasspath && ( "-classpath".equals( arg ) || "-cp".equals( arg ) );
    }

    private boolean isLongModulePathArgument( String arg )
    {
        return  executable.endsWith("java") &&  longModulepath && ( "--module-path".equals( arg ) || "-p".equals( arg ) );
    }

... and of course java.exe and java.bin, although everyone could rename or link their java. If anyone could come up with a better solution, PRs on this PR are welcome!
