Something as simple as one of the examples here would be nice...

It's quite inconvenient. A simple solution like slf4j is also acceptable:
logger.info("the value of {} is {}", name, value);

This issue still exists in GWT Release 2.5.1.

If you code the following:

String foo = "foo";
String bar = "bar";

String foobar = String.format( "Hello %s. Where can I find the %s?", foo, bar);

the gwt compiler fails with:

[ERROR] Line xx: The method format(String, String, String) is undefined for the type
String

Any chance this can be fixed in 2.6.1?

For an implementation to be accepted would it have to conform to the entire Java Formater
spec? http://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html

Would an implementation lacking the Date/Time conversions be acceptable?

Would an implementation that wraps sprintf.js be acceptable (if the licensing is compatible)?
