[jboss-jira] [JBoss JIRA] (LOGTOOL-45) Avoid unnecessary calls to String#format()

[Hardy Ferentschik (JIRA)]

    [ https://issues.jboss.org/browse/LOGTOOL-45?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12686593#comment-12686593 ] 

Hardy Ferentschik commented on LOGTOOL-45:
------------------------------------------

+1 for an option. The overhead for _String#format_ seem considerable. An alternative would be to cache the strings for method calls w/o parameters. This could eg be done once of at class initialization.

> Generated message bundle methods always contain an invocation of {{String#format()}} also if there actually is no parameter to be replaced, e.g. like this:
> {code}
> @Override
> public final String mustNotBeNull() {
>     String result = String.format(mustNotBeNull0$str());
>     return result;
> }
> {code}
> AFAICS the invocation of {{format()}} seems superfluous, instead the String might directly be returned for performance reasons.
