Whats: "error: cannot find file for class"???

[Clemens Eisserer]

Hi there!

Because my xawt-package would overlap with java.awt I renamed my 
packages to java.xawt..... and corrected all the package-descriptions 
and imports.
But since I did this, GCJ throws tons  of the following strange errors:

./java/xawt/image/BufferedImage.java:609: error: cannot find file for 
class java.awt.image.RasterOp
./java/xawt/datatransfer/StringSelection.java:60: error: cannot find 
file for class java.awt.datatransfer.ClipboardOwner
./java/xawt/datatransfer/StringSelection.java:60: error: cannot find 
file for class java.awt.datatransfer.Transferable
java/xawt/ImageNativeProducer.java:0: error: cannot find file for class 
java.awt.image.ColorModel

But in the whole BufferedImage.java is no RasterOp used and line 609 ist 
the last line of this file.
There is no stuff like direct class-use without inports (like 
java.lang.String nm ....)

Whats wrong with my files?
