A problem of vm_channel_class in gnu_java_nio_VMChannel.c

[hultul <hultul@xxxxxxxxx>]

Hi, 

A variable, vm_channel_class, is declared by "static jclass" in gnu_java_nio_VMChannel.c.
The problem is that the variable is used globally, while it is not a global reference.
It is thought that it needs NewGlobalRef() call for vm_channel_class.

Thanks.
