[Hibernate-devel] SortedSet & SortedMap bugfix (?)

[Anton v. S. <an...@ap...>]

I was crashing trying to load a SortedSet, with "java.lang.RuntimeException:
Hibernate failed trying to load a collection".  The log showed that a
ClassCastException was occurring in java.util.TreeMap.compare.  It turned
out that this was because the TreeMap in question didn't have a comparator,
although I had specified one.  I traced this to line 24 of SortedSet.java
(in CVS & v0.9.11):

	java.util.SortedSet clonedSet = new TreeSet();

This looks to me as though it should read:

	java.util.SortedSet clonedSet = new TreeSet(comparator);

...which fixes the problem for me.  There's an equivalent line in SortedMap
which I expect suffers from the same problem.

This problem presumably only occurs if the objects being compared don't
support the Comparable interface - if they do, TreeMap.compare uses that.

I won't make this my first change in CVS, since I haven't attempted to
understand the SortedSet logic in any detail, and for all I know this change
could affect something else.
