Problem solved! Thanks Jake, you got me thinking I found an earlier release of log4j in my classpath. It seems when I upgraded to log4j 1.2.15 recently it got sent to the end of my classpath without me noticing that. The older log4j JAR is included from another project my main project is dependent on and was previously later in my classpath so there was no problem then.
What's curious is that even though the older JAR file came before the newer jar file in the classpath, the compiler was still able to find the right version which supports trace. Phew! I thought I was going insane.

Eclipse is a complex environment and you are almost certainly missing something. I think we can both agree that if Log4j-1.2.15 were in the classpath properly, you wouldn't be getting a NoSuchMethodError because trace() clearly exists in said version of Log4j. Somehow, some way, an older version of Log4j is sneaking into your runtime classpath. Either that, or it's a classloader hierarchy issue, but then I would expect stuff like NoClassDefFoundError and the like.
