Netbeans/Tomcat bug or what?


I had an application working in Netbeans just fine. All of a sudden I get this crazy error after I opened the project with Eclipse. What's going on?

ClassFormatError: Thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file.
