If your component even now must be fixed, Then you can certainly contact its maintainers and ask them to exchange their utilization of JDK-internal APIs with the correct exported APIs.
Enables issuing of membars on thread-condition transitions. This selection is disabled by default on all platforms besides ARM servers, exactly where it’s enabled. (It’s proposed that you choose to don’t disable this feature on ARM servers.)

Sets the Java thread stack size (in kilobytes). Utilization of a scaling suffix, including k, leads to the scaling with the kilobytes worth to ensure that -XX:ThreadStackSize=1k sets the Java thread stack dimension to 1024*1024 bytes or one megabyte. The default worth relies on the platform:
Set the percentage of time (0 to a hundred) accustomed to add conservatism when computing the duty cycle. This option was deprecated in JDK 8 without any replacement, subsequent the deprecation from the -XX:+CMSIncrementalMode solution.

Verifies Individuals lessons that aren’t loaded because of the bootstrap class loader. This can be the default actions if you don’t specify the -Xverify option.
Windows: If the option -agentlib:foo is specified, then the JVM makes an attempt to find this load the library named foo.dll in The situation specified by the PATH technique variable.
