Hello,
Please review the patch below for inclusion into 7u14. Some background
to explain what is going on. The issue 7131459 [1] has already been
fixed in JDK 8 to address some long-standing numerical irregularities in
certain double -> string conversions:
http://hg.openjdk.java.net/jdk8/tl/jdk/rev/bc1f16f5566
However, the patch below does not represent a straight backport of this
work. In the 7 update train, this fix is only going to be used when
7050528 [2] is used and 7050528 is only used in closed code. 7050528 is
a performance optimization with the improved numerical behavior and
7131459 provides consistency in the non-optimized cases.
For the 7 update train, to make this happen some changes are needed in
closed code (not sent to this list), but one small build changes is
needed to an open makefile which controls the building of a jar file
only used in the closed product; patch below:
