Finally made progress on this. There are multiple issues:

- For some reason the generated/ directory, containing only source
files, was explicitly added to the bootstrap classpath by one of our
patches. This is unnecessary, the .class versions are available, but
caused the version of ecj on the machine to "helpfully" try to compile
them. This was easily fixed:

2010-03-01  Mark Wielaard  <mark at klomp.org>

	* patches/ecj/icedtea.patch: Don't add generated dir to
	bootclasspath in langtools/make/build.xml.

That didn't fully fix it, and later on in bootstrapping corba one would
get an unexpected issue with one source file trying to use
sun.security.action.GetPropertyAction. This was caused by a buggy gjar
on the machine. We really should have a configure check to detect this
gjar -u bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36636
For now I added --with-jar=faster to the configure line.

This almost fixes the bootstrap issue, except we are getting:

    [javac] 1. ERROR
in /home/cpdev/icedtea6-build/openjdk-ecj/build/linux-i586/jaxws/drop/jaxws_src/src/com/sun/xml/internal/bind/v2/runtime/unmarshaller/StAXEventConnector.java (at line 279)
    [javac]     String type = staxAttr.getDTDType();
    [javac]                   ^^^^^^^^^^^^^^^^^^^^^
    [javac] Type mismatch: cannot convert from QName to String

This seems to have a fix/workaround in icedtea7
(patches/icedtea-jaxws-getdtdtype.patch). I am testing a backport to
icedtea6

Cheers,
