A DESCRIPTION OF THE PROBLEM :
javadoc no longer overwrites the stylesheet.css file. Some IDEs and build scripts may leave this file in place. If upgrading from earlier versions of Java, the result is incorrectly formatted documentation (Java 6 stylesheet used with Java 7 docs).

Under Java 6, stylesheet.css is overwritten every time documentation is generated.

REGRESSION. Last worked in version 6u26

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Generate any documentation:
   javadoc SomeClass.java
wait a bit, generate again
   javadoc SomeClass.java



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect stylesheet.css to be overwritten and have a new modification date.
ACTUAL -
stylesheet.css is not overwritten and has the old modification date.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
IDEs and build scripts can be modified to delete stylesheet.css before generating documentation.
