[Bug classpath/29010] New: AttributedString checks for defined attributes incorrectly

[cam-gcc-bugzilla at aka dot mcc dot id dot au]

In java/text/AttributedString.java, the check to ensure an attribute is defined
on the current character:

            int rl = aci.getRunLimit(attrib);
            if (rl == -1)
              continue;

is incorrect.  According to the javadoc for AttributedCharacterIterator:

  A run with respect to an attribute is a maximum text range for which:

    * the attribute is undefined or null for the entire range, or
    * the attribute value is defined and has the same non-null value for the
      entire range.

which implies that getRunLimit(AttributedCharacterIterator.Attribute) won't
necessarily return a -1 for an attribute that is not defined, but instead the
limit of the run where it is undefined/null.
