lang/openjdk7 build problems

[Mayuresh <mayuresh%acm.org@localhost>]

I get the following errors when trying to build lang/openjdk7 on NetBSD 6.0 on 
i386.

I have been using openjdk7-bin, though icedtea-plugin was giving some exceptions
with it. I noticed openjdk7 is a newer revision than openjdk7-bin. So thought of
trying.

Also during the build I noticed exceptions related to java awt not being in
classpath. (Do not have exact text. The make did not stop because of those
exceptions.)

Is openjdk7 build known to break or am I missing something on my setup?

Following is the trailing trace.
