This is a problem with the logic selecting the JDKs to use in Derby. You 
can work around it by doing any of:
  a) Set the required ant properties manually (as suggested by Kathey). 
You may have to specify the 1.6 JDK in 'j15lib'.
  b) Remove the gjc installation ([1]).
  c) Add a supported JDK 1.5 installation.
  d) Modify the class called PropertySetter.

Now, the reason why Derby fails to build here is that we are using two 
algorithms to identify/find JDKs we can use.
The first algorithm (the newest one) correctly detects that it cannot 
use the gcj installation. But since the other algorithm is used as a 
fallback mechanism, it is run to find a 1.5 JDK and it incorrectly picks 
gjc.

I planned to make the second algorithm run only if doing that is 
strictly required (i.e. the first algorithm didn't find a 1.6 nor a 1.5 
JDK), but it must have fallen off my plate...

[1] It is not clear to me if what is installed is indeed the complete 
gjc or not. In any case, I don't think it's capable to build Derby yet.
