Would there be any objections to asking the automated builds (that send
messages to the commit list) to use either the latest Sun compiler (5.0_8)
or the Eclipse compiler?
Sun compiler (5.0_8) also has some unexpected behavior. See[1]

There are a number of places that use ReferenceQueues and Reference, but
can't be generified because of a bug in the Sun compilers prior to 5.0_8. At
the end of this email is an example of code that causes a compiler error in
previous releases. This issue does not affect the Eclipse compiler. I've run
a full rebuild as of revision 440796 and everything compiles fine with both
the Eclipse compiler and Sun 5.0_8 compiler.

private static final class CacheEntry extends WeakReference<Object> {
String key;
CacheEntry(Object jar, String key, ReferenceQueue<Object> queue) {
super(jar, queue);
this.key = key;
}
}
// ... code using the queue
CacheEntry entry;
// This cast fails on Sun 5.0_7 and prior compilers
while ((entry = (CacheEntry)cacheQueue.poll()) != null) {
jarCache.remove(entry.key);
}
// . more code
