#3 Pending file handlers

[giocarmine]

I'm using the Transformation Toolkit as a Java library.
I noticed that when you use it for mobile transformation some file handlers remains open.
This problem makes me unable to do things to some of the generated files like to delete them.
As a workaround I used java.lang.Runtime.getRuntime().exec to run Toolkit.jar, so, when his process dies the pending handlers are released.
