I recently updated my Java install on macOS 10.14.4 from Java 10 to Java 11, and the Java System Preference pane disappeared after Java updated. I updated Java again on a different Mac running the same macOS version (10.14.4), and again, the Java System Preference disappeared. I check to see if Java was still installed using
$: java -version, and this is the output I get:
java version "11.0.2" 2019-01-15 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)
This tells me Java is still installed.
Did Oracle discontinue the use of the Java System Preference pane in macOS? I couldn't find anything in Oracle's documentation that would indicated they did.
