[7u40] Request for Phase 2 approval for 7165807: Non optimized initialization of NSS crypto library leads to scalability issue

[Vincent Ryan]

Hello all,

Please approve the following fix for 7u40:

Bug: http://bugs.sun.com/view_bug.do?bug_id=7165807
Webrev: http://cr.openjdk.java.net/~vinnie/7165807/webrev.01/
Code review: http://mail.openjdk.java.net/pipermail/security-dev/2013-June/007786.html
JDK 8 changeset: [under construction]

This fix modifies the SunPKCS11 JCE provider to initialize the Mozilla Network Security Services (NSS)
crypto library to favour performance over memory footprint, by default. A new SunPKCS11 configuration
flag 'nssOptimizeSpace' has been introduced to enable Java applications to revert to the old behaviour.

Note that this change affects only the NSS-specific mode of the SunPKCS11 provider. It makes it consistent
with the provider's regular behaviour which already initializes NSS to favour performance over memory
footprint. 

Thanks.
