and its overloads are supported only for all log levels option.
String templates are evaluated at runtime even when the logging message is not logged; this can negatively impact performance.
It is recommended to use a parameterized log message instead, which will not be evaluated when logging is disabled.
Example (for Kotlin):
val variable1 = getVariable()
logger.info("variable1: $variable1")
After the quick-fix is applied (for Kotlin):
val variable1 = getVariable()
logger.info("variable1: {}", variable1)
Note that the suggested replacement might not be equivalent to the original code, for example, when string templates contain method calls or assignment expressions.
