Thanks Keith. As it happens, I also ran into this one a few days ago. 
The test is >5 years old and only recently started failing for me when I 
picked up the most recent jtreg. Anyway, making the class public, as you 
suggest, fixes the problem so that the test runs. The original intent 
seems to have been to test both the blocking and non-blocking cases and 
there was probably a typo in the original test that went unnoticed. I'll 
get the fix for the test in once the transition to Mercurial is done and 
we start integrating fixes again.  Test aside, we also need to clarify 
the specification for the receive method to state the required behavior 
when invoked on a channel that is unbound. I'll create a bug to track that.
