This error concerns capitalization change of first 
character of inner class name, from upper to lower case, 
only.  I followed these customer supplied instructions and 
reproduced the resulting compile error exactly as they 
described it:

Problem: class files not renamed when case of class name 
changes

Test case: This file below was originally named 
class "productElement" with an initial capital "P". The 
class was compiled, resulting in a compiled file 
AmazonQueryResult$ProductElement.class. The case change
was made to the productElement class and the class was 
recompiled successfully. A new version of 
AmazonQueryResult$ProductElement.class was created. 
However, the case of the generated .class file was not 
changed to reflect the new class name.

About box:
Forte for Java 4, Enterprise Edition (Build 020521)
Java VM 1.4.0-b92 on Windows

fragment of code that shows the error:

AmazonQueryResult queryResult = new AmazonQueryResult();
queryResult.catalog.product.title = "title";

The second line generates the following compile error:
 org/dyck/bookdatabase/amazonqueryservice/AmazonQuery.java 
[69:1] cannot access
 
org.dyck.bookdatabase.amazonqueryservice.AmazonQueryResult.
productElement file
 
org\dyck\bookdatabase\amazonqueryservice\AmazonQueryResult$
productElement.class not found
       queryResult.catalog.product.title = "title";

Removing the .class files and rebuilding 
AmazonQueryResult.java produces a class file for the inner 
class with the correct case.
