I am trying to bridge a LogRecord with a message that is the result of HashMap.toString():

{interface com.google.code.morphia.annotations.Id=@com.google.code.morphia.annotations.Id()}

and get following exception

Caused by: java.lang.IllegalArgumentException: can't parse argument number interface com.google.code.morphia.annotations.Id=@com.google.code.morphia.annotations.Id()
at java.text.MessageFormat.makeFormat(MessageFormat.java:1339)
at java.text.MessageFormat.applyPattern(MessageFormat.java:458)
at java.text.MessageFormat.<init>(MessageFormat.java:350)
at java.text.MessageFormat.format(MessageFormat.java:811)
at org.slf4j.bridge.SLF4JBridgeHandler.getMessageI18N(SLF4JBridgeHandler.java:233)

FIX: do not format since there are no parameters!

if (params != null && params.length > 0)
