Unfortunately, there are still problems with running JVM backend tests
with JVM target 21 because:
1) The D8 version that we use does not support bytecode version 21, and
updating to a newer version requires to change JVM target of compiler
tests to 11. This will be addressed separately when we enable JVM 21
in tests-different-jdk.
2) Some tests are failing because of KT-60659 and KT-60770:
- builtinStubMethods/bridgesForStubs/emptyStringListAdd.kt
- jdk/stream.kt
- regressions/kt528.kt
#KT-60662 Fixed
