> This problem is due to the fact that the class ProcessImpl is not exactly
> identical to the interface java.lang.Process signature. If you set the
> override to true in the method object (using AccessibleObject.setAccessible)
> you will be able to invoke the method. This works in the JRE 8 xsl
> transformer.
