title: Java8 and Aspectj plugin are not compatible?
body: <p>I'm using eclipse Kepler 4.3.2 with STS, Maven and other Web development tools. Today i thinked about trying some lambdas with Java 8, so I installed JDK1.8 and Eclipse Plug-in Development Environment Patch with Java 8 support (for Kepler SR2). It was working but when I opened project i was working with I got bunch build errors in dispatcher-servlet.xml:</p>
  
  <p>Build path is incomplete. Cannot find class file for org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException</p>
  
  <p>It looked like AspectJ plugin was uninstalled, so I installed it again:
  AspectJ Development Tools (AJDT) including the AspectJ compiler.
  AspectJ compiler for Eclipse</p>
  
  <p>After rebuiling, project works again but I cant use lambdas. In preferences > Compiler compliance level there isn't Java 1.8. It was there before installing AspectJ stuff.</p>
  
  <p>What can I do to make this work together?</p>
