[Bug classpath/22639] bug in java.text.MessageFormat.format(Object[], StringBuffer, FieldPosition)

[gcc-bugzilla at gcc dot gnu dot org]

A spurious IllegalArgumentException is thrown if there are multiple
ChoiceFormats in the pattern.  I've attached a test program which reproduces
the bug.  Here is a patch to (hopefully) fix the problem:

diff -u -r1.1 MessageFormat.java
--- MessageFormat.java  2002/06/24 13:56:20     1.1
+++ MessageFormat.java  2002/06/28 20:34:52

                mf.applyPattern(buf.toString());
-               formatter = mf;
+               mf.format(arguments, appendBuf, ignore);
              }

+           else
+             formatter.format(thisArg, appendBuf, ignore);
          }

        appendBuf.append(elements[i].trailer);

I don't see the test program.
Could you send it?

I've checked in the fix for this.
I also checked in a follow-on fix for another bug revealed
by the test.
Finally, I put the test itself into Mauve.
