I had this problem when running against JDK 1.6 on the Linux platform (though it worked on windows JDK 1.6 I think). It may be that the backport-concurrent library is not compatible with Linux JDK 1.6.
In order to fix this, I went ahead and took out backport-concurrent on our local Tapestry 4.1.1 build. This was as easy as deleting the string 'edu.emory.mathcs.backport.' across the entire code base (and removing the dependency from the pom.xml files). Of course, now our local Tapestry build *requires* Java 6.
