It is a professional attribute that requires you to definitely also specify the -XX:+UnlockCommercialFeatures solution as follows:

This ratio is utilized when the -XX:+UseRTMDeopt alternative is enabled. The default price of this feature is 50. This means that the compiled code is deoptimized if 50% of all transactions are aborted.

The choice was removed, because the total incremental mode was removed.

Linux only: This feature may be the equivalent of specifying -XX:+UseLargePages. This selection is disabled by default.
