Re: Fwd: Status of gcj/java on PPC Linux?

Hi,

I used gdb to track back the cause of gij not being able to find the class.

The problem seems to come in gcc/libjava/java/net/URLClassLoader.java in line 
250.

The file was found correctly, the io stream was opened and read but just but 
just as we are about to return an object:

Line 250       return defineClass (name, data, 0, len);

The code goes to create and object and then to the dl-linker and seems to die 
out there someplace.

Anyway, I can't continue to debug the closure interface without being able to 
at least load a class.

Any help you might have here would be greatly appreciated.

Thanks,

Kevin
