What version of Eclipse are you using? Java 5.0 is only supported from v3.1 and up. Also when you start the project you have to make sure that it is set to the 1.5 VM.

Properties-->Java Compiler-->Compiler compliance level-->5.0

well i have chosen 5.0 but it does not like java.util.concurrent.Semaphore
it just does not know what it is....
Do you also have a v1.5 JDK installed? Also make sure it is selected in the project library settings. It should say JRE System Library[jdk5.0]
