Small URLClassLoader bug fix

[Jeroen Frijters]

Hi,

After getting the latest code from CVS, I ran into a problem
(ClassFormatError). Turned out to be due to a small bug in
java.net.URLClassLoader.

<                 in.read(classData);
---
>                 int pos = 0;
>                 while(length - pos > 0) {
>                     pos += in.read(classData, pos, length - pos);
>                 }

Regards,
Jeroen
