John,
I looked at the changes that you have here:
http://cr.openjdk.java.net/~chegar/8001579/webrev.01/
and it's great to get these warnings finally fixed.
The changes look okay to me and I assume that someone in the security
group will sponsor this.
Two comments:
In Java_sun_security_jgss_wrapper_GSSLibStub_getMechPtr then I wonder if
additional casts are needed for len as GetArrayLength returns a jsize
and memcpy expects a size_t.
You might want to check with Vinnie on
src/share/native/sun/security/ec/impl/mpi.c as there may be a desire to
keep this code in sync with the upstream EC code
-Alan.
