I have two tomcat instances on my windows machine and both run the same code and point to the same font directory. Both of these instances use the same Java runtime environment. I get this error with only one of my instances. (I can confirm that the configurations for both are absolutely similar)

Again, as I mentioned already, I did try the Allfonts.jar provided by pd4ml @ http://pd4ml.com/i/allfonts.zip which also generates the same error.
