The flight recorder has been available also in JDK8 (docs.oracle.com/en/java/java-compo...)
The "var" (local type inference) has been introduced in JDK 10 (openjdk.org/projects/jdk/10/) and not in JDK 11.
For changes in the API I strongly recommend to check: javaalmanac.io/jdk/11/apidiff/8/ (from 8 to 11) and javaalmanac.io/jdk/17/apidiff/11/ (from 11 to 17)...
In JDK 10:
mapMultiToDouble
Just to mention a few...
String.repeat, String.lines, String.strip have been introduced in JDK 11 and not in JDK 17...
(javaalmanac.io/jdk/11/apidiff/8/)
String.transform (JDK12)
String.stripIndent,String.translateEscapes,String.formatted in JDK 15,
