FULL PRODUCT VERSION :
java full version "1.6.0-b105"


ADDITIONAL OS VERSION INFORMATION :
Generic

A DESCRIPTION OF THE PROBLEM :

Problem with duplicate errors being output.
javac warns that the class name doesn't match the file name.
When run with a empty processor, the identical error gets output twice.
See transcript below.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create the two source files as declared later and follow the steps in expected results.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -

% javac -version
javac 1.6.0
% javac One.java
One.java:1: class Two is public, should be declared in a file named
Two.java
public class Two { }
      ^
1 error
% javac EmptyProcessor.java
% javac -processor EmptyProcessor One.java
One.java:1: class Two is public, should be declared in a file named
Two.java
public class Two { }
      ^
One.java:1: class Two is public, should be declared in a file named
Two.java
public class Two { }
      ^
1 error

ACTUAL -
Get one error message in both cases.

REPRODUCIBILITY :
This bug can be reproduced always.
