Code Review Request: 8063700 -Xcheck:jni changes cause many JCK failures in api/javax_crypto tests with SunPKCS11

[Anthony Scarpino]

Hi,

I need a review of this change to the pkcs11 wrapper code.  The changes 
allow encryption to work properly when -Xcheck:jni is called.   A recent 
change to -Xcheck:jni caused the failures to occur.
