The current JDK PKCS11 code creates native keys by iterating over PKCS11 attributes and allocating memory to represent data where necessary. These allocations are not always 64-bit aligned and that can be a performance hit for some architectures when accessing certain data types. On Solaris SPARC, it can cause SIGBUS - seen in JDK 11u testing.
