Code review request for 6988081 and 6850402

[Valerie (Yu-Ching) Peng]

Hi, Vinnie,

Do you have the cycles to review the following two fixes?
1) 6988081: Use GetPrimitiveArrayCritical instead GetByteArray to Reduce 
allocation in some sunpkcs jni wrappers
http://cr.openjdk.java.net/~valeriep/6988081
Note: verified by Alejandro who ran the SPECjvm benchmark

2) 6850402: Deadlock on sun.security.jca.ProviderConfig starting from 
jdk7-b55
http://cr.openjdk.java.net/~valeriep/6850402
Note: verified by re-running the failed stress test

Thanks,
Valerie
