There are some issues with HEAD I need to look at, that's why there
hasn't been a new release yet.  Have you tried 1.12?

This is true of a lot of classes.  We pre-build them before entering
the OpenJDK build to get round this.  I'll have to look at your logs
to see why this is not being built here.

Use --disable-bootstrap when using OpenJDK6.  A full bootstrap cycle
with OpenJDK is not yet supported.
