SLF4J / SLF4J-371 [Resolved] Support the lambda expression in the Logger ============================== Here's what changed in this issue in the last few minutes. There is 1 comment. View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-371 ============================== 1 comment ------------------------------ Alexander Kiselyov on 27/Dec/21 4:57 PM Just to make things clear: the last listing won't work either - it'll just print the standard {{Object.toString()}} return value ({{ getClass().getName() + '@' + Integer.toHexString(hashCode())}}) :) Reason is, {{Callable}} interface is not the same as {{Supplier}} (though signature is quite similar), and, hence, your resulting anonymous class does not implement it, so {{addArgument(Object)}} will be invoked instead of {{addArgument(Supplier<?>)}}. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
