----------------------------------------------------------------

FYI (for anyone that cares) ...
The workaround:
---------------------------
{code}
import org.slf4j.Logger
import org.slf4j.LoggerFactory

import groovy.transform.CompileStatic
import groovy.util.logging.Slf4j

//@Slf4j("LOG")
@CompileStatic
trait TTest {
  final static Logger LOG = LoggerFactory.getLogger(TTest.class)

  void test1() {
    LOG.debug("Logging test1 ...")
  }

  void test2() {
    ((Logger)LOG).debug("Logging test2 ...")
  }
}
{code}

The workaround:
---------------------------
```
import org.slf4j.Logger
import org.slf4j.LoggerFactory

import groovy.transform.CompileStatic
import groovy.util.logging.Slf4j

//@Slf4j("LOG")
@CompileStatic
trait TTest {
  final static Logger LOG = LoggerFactory.getLogger(TTest.class)

  void test1() {
    LOG.debug("Logging test1 ...")
  }

  void test2() {
    ((Logger)LOG).debug("Logging test2 ...")
  }
}
