Environment

IntelliJ IDEA 2022.1.3 (Ultimate Edition)

Additional context

Adding the following lines to build.gradle fixes this conflict:

sourceCompatibility = 11
targetCompatibility = 11

[alisevych]

Same exception is thrown in IDEA project with JDK 13.
So here are both stacktraces:
IDEA stacktrace.txt
Gradle stacktrace.txt

[sergeypospelov]

This issue should be already fixed by #1067.
