No worries, hope everything is okay for you now.

Could you elaborate on what you mean by 'conflicting types'?

I didn't try the bootstrap-with-icedtea option myself so far, just the
existing options (bootstrap-with-gcj, no-bootstrap-with-icedtea) to
make sure we didn't regress.  I left out the tools.jar chunk of the
patch because I wasn't sure about it.

There's a bit of history to the whole tools.jar situation.  The ecj
build originally created a tools.jar as well (in a similar way to the
current rt.stamp target and friends) but it resulted in a lot of
additional confusion and duplication of compilation with little
benefit.  So the bootstrap was changed to pack all the bootstrap
classes in an updated rt.jar from the system jdk.  tools.jar only
actually needs to exist for an existence check by HotSpot.  IcedTea6
currently satifies that by a symlink to rt.jar, as you've seen, but I
think I'll switch it to patching HotSpot during bootstrap as I've done
in IcedTea7.

This works fine for the existing configurations but breaks with
bootstrapping with IcedTea.  Why? Well...

1.  The necessary sun.* classes are built in the rt.stamp stage.  However,
this only happens if sun.awt.Toolkit is not found (which is used to signify
that the bootstrap JDK has Sun classes).  See
> checking if sun.awt.SunToolkit is missing... no
in your output.

2.  Of course those classes are available in your JDK but in tools.jar not
rt.jar.  The javac invocation looks at tools.jar but because we don't symlink
the whole system JDK to bootstrap/jdk1.6.0 (as in the second stage), it's
not accessible from the build.

Thus, your fix seems appropriate and I'll add the symlink to tools.jar
if it exists.  I'd be very interested to know what issues you had with
doing this.

If you're wondering why the bootstrap build doesn't just link the system
JDK, it's so we can override its javac with the Perl script used by IcedTea
which contains a number of workarounds to make ecj look like javac.
