Custom Rules for Package Names in JDT 3.6 M7
Deepak Azad has blogged about some of the new features available in the JDT 3.6 M7 release.
Now, package names in Java views can be abbreviated with custom rules, in addition to Eclipse's package name compression preference of 'org.eclipse.ui.contentassist' being compressed to 'o.e.u.contentassist'. There is also a new decorator on Java projects and working sets that contain build path errors, which should help in the identification of build path problems.
Please see his blog for more information on both new features.
