- Lincheck is compiled with JDK 11 and the `low-level-api-fir` module is based on the JDK 8 toolchain, so we need to add a new module with a JDK 11 toolchain to support Lincheck tests. We cannot bump `low-level-api-fir` to JDK 11 because `low-level-api-fir-for-ide` requires it to be based on a JDK 8 toolchain. - Using a Gradle test suite is unfortunately not an option, because `low-level-api-fir-for-ide` will think that the whole `low-level-api-fir` module is compiled with JDK 11 if just a single test suite has this toolchain. ^KT-62136
