A warning is shown if the signature is not time stamped. See Signing JAR Files for information. The Type Inference section in the Generics trail has been updated with the section Target Types, which describes how the Java compiler takes advantage of target typing to infer the type parameters ...

you have to break it again first. In many ways, Java has set wrong. Property access is just one example. Sooner or later we’re going to have to admit that it’s time to start over and create a new Java 3 that makes a clean break...
Generally ThreadLocal instances are private static fields in classes (e.g.,we may associate a user ID or Transaction ID etc). Frameworks generally use threadlocal to store context related data. Using Generics in ThreadLocal. After java 1.5 we can use Generic notation in the ThreadLocal declarat...
