A DESCRIPTION OF THE PROBLEM :
The getVersionString(File f) method of sun.awt.motif.MFontConfiguration creates a java.util.Scanner but does not close it. The end result is that a input stream is left hanging around until such time as it is garbage collected.

I believe this can be trivially fixed by adding scanner.close() as a finally clause in the getVersionString(File f) method.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Observing the effect is somewhat difficult unless you have an application which needs to write to a very high number of simultaneous streams.
