BigDecimal's divide(BigDecimal bd, RoundingFormat r) produces incorrect result

FULL PRODUCT VERSION :
Occurs on JRE 6 updates 14 and 16. It does not occur for 13 or 05. Also doesn't occur for JRE 5. JDK doesnt seem to matter.

ADDITIONAL OS VERSION INFORMATION :
SunOS noc5pbbatchdev2z1 5.10 Generic_137137-09 sun4u sparc SUNW,Sun-Fire-V490

Microsoft Windows XP [Version 5.1.2600]

(Found error on both.)

A DESCRIPTION OF THE PROBLEM :
Doing regression testing with switch from java 5 to java 6 we came across a discrepancy between bigdecimal results of divide. Based on the javadocs, the three divide method invocations below should correctly round the result up to 0.000115309916. However, they are not doing that. They are either rounding down or truncating or otherwise messing up, and are always giving a 5 as the last digit, rather than a 6. Further investigation determined that this was an issue with JRE 6u14 and u16, but did not occur with JRE6u13 or u05, and jdk doesnt seem to matter.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Get JRE 6u14, or u16. (Good chance everything u14+ will have the bug in it.) Use JDK 6u16 (although i dont believe jdk matters.) Then run the code below.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
div1: 0.000115309915
div2: 0.000115309915
div3: 0.000115309915
ACTUAL -
div1: 0.000115309916
div2: 0.000115309916
div3: 0.000115309916

REPRODUCIBILITY :
This bug can be reproduced rarely.
