I would recommend using 'hg id', not 'hg tip':1. If the developer has updated to a specific revision and built it, 'hg id' would be accurate, but 'hg tip' would be meaningless.
2. If there are local modifications, 'hg id' will record that fact (with a '+'), which is good to know.
It will also include tag information, which may or may not be desirable.I would expect 'java -version' to include the changeset ID, if it were built from sources and was not a formal release.
TREES:=$(shell hg ftrees)
Or could just search for direct subdirs with .hg subsubdirs. A lot faster, does not use the forest extension, and should work for the OpenJDK forest at least.
