recently I started learning the wonders of AspectJ (http://www.eclipse.org/aspectj/doc/released/faq.php) and decided to use it on a program.
To start I downloaded the lates stable version of aspectJ (http://www.eclipse.org/aspectj/downloads.php#stable_release). Then I decided to install AspectJ's plugin for eclipse (http://www.eclipse.org/ajdt/whatsnew220/).
I am using eclipse (Version: 3.8.0 Build id: I20120502-2000) and currently I don't have any other plugins installed.
However, when I try to create a .aj file or to save changes in one I always get this error:
Save Failed
org.eclipse.ajdt.core.javaelements.AJCompilationUnit.openWhenClosed(Ljava/lang/Object;Lorg/eclipse/core/runtime/IProgressMonitor;)Ljava/lang/Object;
What is wrong with my installation and what can I do to fix it?
