Support for SLF4J 2.x #918

Open hohwille opened 1 month ago

hohwille commented 1 month ago

The SLF4J Logger API has been extended in version 2.x and now supports fluent logging: https://www.slf4j.org/manual.html#fluent

When using this in a library that ends up in client code then TeaVM fails with such error:

[INFO] Running TeaVM

Method atLevel and according stuff needs to be implemented here: https://github.com/konsoletyper/teavm/blob/d40bd9989b36578b08d8f3a58d89070593d7c82e/classlib/src/main/java/org/teavm/classlib/java/util/logging/TLogger.java#L27
