java.lang.InternalError: fillbuf ????

[Juan Manuel Fernández Luna]

Can anybody help me? I'm desperate!!!

I'm writing a program in Java to deal with xml files and when the file
volume.xml (attached) is being parsed, the following exception occurs
and I don't what the problem is.

Please, if you know why it happens or a site where I could ask, tell me.

Best,
Juanma
