Code review request for 6850402 and 6887853

[Valerie (Yu-Ching) Peng]

Hi, Sean,

Do you have time to review these two fixes?

6850402: Deadlock on sun.security.jca.ProviderConfig starting from jdk7-b55
http://cr.openjdk.java.net/~valeriep/6850402
Note: verify by re-running the stress test

6887853: javadoc for java.lang.Classloader should be more clear
http://cr.openjdk.java.net/~valeriep/6887853
Note: javadoc re-wording only; will file CCC after changes being reviewed

Thanks,
Valerie
