I can confirm this. If I configure icedtea-web with icedtea6-1.8, I get 
the same failures. If I use an icedtea6-1.10 (or later I presume) build, 
things work fine.

An error like this normally indicates that package-private classes are 
loaded by different class loaders. When running a 'make check' the 
application classloader is used to load both netx.jar (or it's renamed 
version classes.jar) and the test code. If netx.jar is in the 
bootclasspath, however, then the JVM loads it from there and you get 
this problem because two classes in the same package are now being 
loaded by different classloaders.
