Java 7 Support in Eclipse JDT (BETA)

Java 7 is not publicly released yet and hence the Eclipse Java 7 support could not be shipped with 3.7 or 4.1. However those who want to use it in 3.7 or 4.1 can do it using the install instructions mentioned on

If you find a bug or have ideas on new quick fixes / refactorings / templates / ... , please file a bug with the [1.7] tag !

I should add that this is a work in progress, and more details are available on the following two wiki pages

Note: This is an implementation of an early-draft specification developed under the Java Community Process (JCP) and is made available for testing and evaluation purposes only. The code is not compatible with any specification of the JCP.

JDT Tip: See different hovers in Java editor by using modifier keys

  •  When you move the mouse over an identifier that has no error or warning, by default a hover with the Javadoc is shown. 

  • However if there is an error or a warning on the identifier then the corresponding message is shown.

  • To see the Javadoc even in this case, you can enable the Javadoc hover on this preference page and define a key modifier e.g. Ctrl+Shift. 
  • Now press Ctrl+Shift while hovering to see the javadoc.

JDT Tip: Mark Occurrences in Java editor

I think everyone knows that the Java editor highlights occurrences of variables and method calls.

But did you know that it also highlights
  • Method exit points - select (or place caret in) the method return type

  • Method calls or statements throwing an exception - select (or place caret in) an exception in a catch block

  • Break/Continue targets - select (or place caret in) break or continue keywords
