In the langtools build, the genstubs tool is passed a classpath: <genstubs srcdir="${import.jdk.src.dir}" destdir="${build.genstubs.dir}" includes="${import.jdk.stub.files}" fork="true" classpath="${build.toolclasses.dir}:${build.bootstrap.dir}/classes:${ant.home}/lib/ant.jar" />
which it uses for a forked process that runs genstubs itself. However, if fork is set to false the classpath given by: <taskdef name="genstubs" classname="GenStubs$$Ant" classpath="${build.toolclasses.dir}/"/> which seems to work in some cases, but only if Ant has access to the 1.6 javax.tools classes. Even if these classes are available, they will be the ones belonging to the boot VM and not the bootstrap classes. Should this classpath not be set to the same as that passed to genstubs as in http://hg.openjdk.java.net/icedtea/jdk7/langtools/rev/681f1f51926f ? -- Andrew :-) Free Java Software Engineer Red Hat, Inc.
