[fedora-java] Bug in openjdks TreeMap?

[Christoph Höger]

Hi,

I enounter a very odd behaviour of a TreeMap. This is the code fragment:

			System.err.println("contains: " +
state.getIndexMap().containsKey(termString));
			for (TerminalString term : state.getIndexMap().keySet())
				System.err.println("KEYS: " + term + "==" + termString +":" +
term.equals(termString) + " compare: " +
state.getIndexMap().comparator().compare(term, termString));

The TreeMap returned getIndexMap contains mappings from TerminalString
to Integer.
This is the output:

contains: false
KEYS: redeclare (1581148120) ==redeclare (1581148120) :true compare: 0

So the key _is_ in that map. It also has the very same hashcode and the
comparator returns 0 and equals() is true. But still containsKey returns
zero.
Any guess why that?
