On MIPS platforms (and probably others) unaligned memory access results in a
bus error. In the connect storage engine, block data for some data formats is
stored packed in memory and the TYPBLK class is used to read values from it.
Since TYPBLK does not have special handling for this packed memory, it can
quite easily result in unaligned memory accesses.
The simple way to fix this is to perform all accesses to the main buffer
through memcpy. With GCC and optimizations turned on, this call to memcpy is
completely optimized away on architectures where unaligned accesses are ok
(like x86).

Solution suggested by wlad@mariadb.com
- `JNI_FOUND` is a internal result variable and should be set with
cached library and header variables (like `JAVA_INCLUDE_PATH`) defined.
* Note: wrapper cmake/FindJNI.cmake runs first time and cmake native Find<module> returns only cached variable, like `JAVA_INCLUDE_PATH`, results variable are not cached).
