Description

After I create a new Java source file using vanilla javac (i.e. not nb-javac), and change the name of the class within the class signature (i.e., not by renaming the file or by doing refactoring, but just by typing a different name in the class signature in the Java source file), the error below is thrown:

com.sun.tools.javac.code.ClassFinder$BadClassFile: bad source file: MyApp1.java
file does not contain class myapp1.MyApp1
Please remove or make sure it appears in the correct subdirectory of the sourcepath.
