[8u20] RFA: 8032909: XSLT string-length returns incorrect length when string includes complementary chars

[Aleksej Efimov]

Hello,

I would like to request for approval to push a straight-forward backport 
of the fix from JDK 9 to JDK 8 into jdk8u-dev repository.

Bug:
https://bugs.openjdk.java.net/browse/JDK-8032909

JDK 9 changesets:
http://hg.openjdk.java.net/jdk9/dev/jdk/rev/94320b16ec02
http://hg.openjdk.java.net/jdk9/dev/jaxp/rev/4d48033d8d1d

JDK 9 review thread:
http://mail.openjdk.java.net/pipermail/core-libs-dev/2014-February/025220.html

Thank you,
Aleksej
