This section describes changes that are required if you are trying to change your 3.7 plug-in to adopt the 3.8 mechanisms and APIs.
A new AST level
org.eclipse.jdt.core.dom.AST#JLS4 has been added for Java 7 language changes.
Clients of previous AST levels are recommended to adopt the new AST level and add support for the new constructs
TryStatement#resources() / #RESOURCES_PROPERTY).
org.eclipse.jdt.core.compiler.ReconcileContext#getAST4() should be used were possible.
org.eclipse.jdt.ui.SharedASTProvider#getAST(..) now returns a JLS4 AST.
Note that these changes only affect products moving from Eclipse 3.7.0 to 3.7.1 or 3.8. Eclipse 3.7.1 and later already contain these changes.
