Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_08-b03)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
Using the DecimalFormat(String) constructor:

If the pattern contains a negative sub-pattern that does not exactly reproduce the positive sub pattern (with prefix/suffix) the suffix of the negative patten is lost.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the program that's given below.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected the close paren to appear as the negative suffix for every pattern.
ACTUAL -
in pat #0.0#;(0) out pat #0.0#;(#0.0# neg prefix ( neg suffix  -1.1 (1.1
in pat #0.0;(#) out pat #0.0;(#0.0 neg prefix ( neg suffix  -1.1 (1.1
in pat #0.0#;(#) out pat #0.0#;(#0.0# neg prefix ( neg suffix  -1.1 (1.1
in pat #0.0#;(#0.0#) out pat #0.0#;(#0.0#) neg prefix ( neg suffix ) -1.1 (1.1)

REPRODUCIBILITY :
This bug can be reproduced always.

    for (int i = 0; i < pats.length; i++) {
      String s = pats[i];
      DecimalFormat df = new DecimalFormat(s);
      System.out.println("in pat " + s +
