Can't build latest openjdk6

The version of java using ant being significant
means there are 3 different java versions being juggled during
a single build - it's easy for us all to get very confused.

I'm going to try to stay in bug-reporting mode, not bug-fixing mode,
with this problem unless Jonathan/Kelly/Joe can't reproduce the failure.
