Cannot use ECJ 3.36.0 to compile Java 17 sources

[UdoW]

I set in my build.gradle the ECJ version to 3.36.0 to use it for compiling Java 17 source files.

I get this error:

$ ./gradlew build

> Task :compileJava FAILED
source level should be comprised in between '1.3' and '1.8' (or '5', '5.0', ..., '8' or '8.0'): 17

Is compiling Java 17 source code not possible?

Hi @UdoW, could you please share your build script or, ideally, an MCVE?

Closing as I cannot reproduce this issue and did not receive an MCVE.
