Loading of the zlibnx library on AIX is disabled by default

From release 0.25.0 onwards, zlibNX hardware-accelerated data compression and decompression was enabled by default on AIX®. From this release onwards, loading of the zlibnx library on AIX is disabled by default because using zlibNX might cause a ClassNotFoundException error. You can enable adding of the zlibNX library by using the -XX:+UseZlibNX option.

For more information, see -XX:[+|-]UseZlibNX.
