When something starts working for a reason unknown, beware ...

That wasn't the problem after all.  I'm seeing this again in a merged
Jigsaw+M5 forest.

After enabling some ant verbosity I found that, when building jaxws,
ant defines the javac -classpath argument as

    $BUILD/jaxws/build/classes:${RANDOM_ANT_JARS}:$BUILD/bootjdk/j2sdk-image/lib/tools.jar

in a plain M5 build.  In a Jigsaw+M5 build, however, the tools.jar
element is omitted, which certainly explains the failure I'm seeing.

Can someone with more ant expertise than I suggest how to proceed?

Full logs available on request.
