[Bug awt/26391] New: drawImage assertion warnings, missing image repaints, and crashes

[hendrich at informatik dot uni-hamburg dot de]

I just re-built Classpath cvs (2006.02.21) and tried to run my usual test
applications via JamVM on Linux x86.

(1) The image viewer now triggers lots of assertion failures
    (see below). 

(2) Also, every second image repaint is lost somehow; the image
    seems to be correctly loaded, but rendering only takes place when manually
    enforcing a repaint (e.g. window resizing). 

(3) Even worse, the application
    now crashes randomly (usually after browsing to about 20..30 images).
    So far, I have not been able to get a useful backtrace; will try to 
    post one as time (and motivation) allows. One way to enforce the crash
    is to click one of the "(sub)directory" thumbnail images
    in the thumbnails canvas.
