FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
According to the Javadoc, a pattern like "0.00;(#)" should be the same as "0.00;(0.00)". However, I wrote a unit-test that shows different and everything after the '#' is not included in the result.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Add the following unit-test to a JUnit or TestNG testcase:

    public void testJavaDecimalFormat() {
        DecimalFormat format = new DecimalFormat("0.00;(0.00)");
        assertEquals("5.00", format.format(new Integer(5)));
        assertEquals("(5.00)", format.format(new Integer(-5)));

        format = new DecimalFormat("0.00;(#)");
        assertEquals("5.00", format.format(new Integer(5)));
        assertEquals("(5.00)", format.format(new Integer(-5)));
    }


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected were no failures.
ACTUAL -
The last assertEquals fails with the message:
expected <(5.00)> but was <(5.00>


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
    public void testJavaDecimalFormat() {
        DecimalFormat format = new DecimalFormat("0.00;(0.00)");
        assertEquals("5.00", format.format(new Integer(5)));
        assertEquals("(5.00)", format.format(new Integer(-5)));

        format = new DecimalFormat("0.00;(#)");
        assertEquals("5.00", format.format(new Integer(5)));
        assertEquals("(5.00)", format.format(new Integer(-5)));
    }

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Write the negative subpattern completely, don't rely on the single '#'.
