What do 'Deprecated', 'Obsoleted', and 'Expired' mean?

Definitions abridged from the OpenJDK source code file src/hotspot/share/runtime/arguments.cpp

Using the example of -XX:+AggressiveOpts which was Deprecated in JDK11, Obsoleted in JDK12, Expired in JDK13.

Deprecated

An option that is supported, but a warning is printed to let the user know that support may be removed in the future.

./jdk11/build/linux-x86_64-normal-server-release/jdk/bin/java -XX:+AggressiveOpts
OpenJDK 64-Bit Server VM warning: Option AggressiveOpts was deprecated in version 11.0 and will likely be removed in a future release.

Obsoleted

An option that has been removed, but is still accepted on the command line. A warning is printed to let the user know that option might not be accepted in the future.

./jdk12/build/linux-x86_64-server-release/jdk/bin/java -XX:+AggressiveOpts
OpenJDK 64-Bit Server VM warning: Ignoring option AggressiveOpts; support was removed in 12.0

Expired

A deprecated or obsolete option that has an "accept_until" version less than or equal to the current JDK version. It will just print a warning when used in the JDK version in which it expired.

./jdk13/build/linux-x86_64-server-release/jdk/bin/java -XX:+AggressiveOpts
OpenJDK 64-Bit Server VM warning: Ignoring option AggressiveOpts; support was removed in 12.0

Once you go past the JDK version in which the option was expired the VM will fail to start when the option is passed:

Using the example of -XX:+DeferPollingPageLoopCount which was Deprecated in JDK10, Obsoleted in JDK11, Expired in JDK12.

./jdk13/build/linux-x86_64-server-release/jdk/bin/java -XX:+DeferPollingPageLoopCount
Unrecognized VM option 'DeferPollingPageLoopCount'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
