Description
After the fix for JDK-6913047 we have a large number of crashes on Solaris

Fix Request JDK-8 will be affected by this bug after backporting JDK-6913047. Patch applies cleanly, except for P11Key.java part (which simply reverts JDK-8217088).

No new regression test as this is reproducible with running existing regression tests on Solaris-Sparc v9 under the jdk-tier4 target. Thus adding the @noreg-other label.

The SIGBUS is caused by dereferencing the "wrappedKeySizePtr" variable which is declared to be (unsigned long*). Its pointer address is calculated as (nativeKeyInfoArrayRaw + sizeof(unsigned long)*2 + totalCkAttributesSize + totalDataSize) which may become un-aligned depending on the value of "totalDataSize". The simplest fix is to change the declaration of wrappedKeySizePtr to (jbyte*). Just to be safe, I have also changed another unsigned long* to use jbyte* and made corresponding adjustments. http://cr.openjdk.java.net/~valeriep/8216597/webrev.00/ Mach5 job with jdk-tier1, jdk-tier2, and jdk-tier4 completed w/ all tests passed.

[~mbalao], please look at this soon as it is causing test failures - thanks.

This code looks suspicious: wrappedKeySizeWrappedKeyArrayPtr = (unsigned long*)(nativeKeyInfoWrappedKeyArrayRaw + sizeof(unsigned long)*2 + totalCkAttributesSize + totalDataSize); The resulting address will need to be 64-bit aligned.
