you could always set the compiler bootclasspath, as mentioned here: http://docs.codehaus.org/x/9fE so no matter what JDK you use, it will compile against the right classlib: <configuration> <source>1.3</source> <target>1.3</target> <compilerArguments> <bootclasspath>${some.property}/path/to/some/rt.jar</bootclasspath> </compilerArguments> </configuration> then it's just a matter of getting the relevant rt.jar and either putting it in a repository, or providing it as part of your project / developer setup.
