[kaffe] tomcat3.2.3 doesn't work properly on Kaffe-1.0.6-6

[Godmar Back]

 Btw, if you don't want to wait for Dalibor to check in the proper
1.2 application class loader stuff, you could also resurrect a change
Tim had suggested 4 years ago; see
$ cvs diff -r1.2 -r1.3 Class.java

I had rejected it back then because it broke JDK 1.1 compatibility,
but I suppose that's no longer important.  Back then, some applications
relied on the opposite behavior (i.e., getClassLoader() returning null).

This might fix the breakage with zero classloaders passed to Hashtable.put.
