All of the image loading apps that we tried are badly broken in JDK 1.1.5K
For example - the two caffeinemaek 2.5 tests
(Graphics and Image).

The images do not display (blank blue screen) unless
the window is resized to full screen size.

This was verified on Sparc Solaris 2.5.1 and SGI Irix

I have also verified that this all worked in 1.1.5G, but was broken in 1.1.5J

This is a pretty fundamental bug, I can't imagine shipping this as FCS

Additional information from customer, sheri.good@Eng 1997-12-10:

The platforms where we had trouble were:

1. Solaris running OpenLook WM
2. SGI irix using a Motif mwm-derived manager

For 2, we did have to integrate with our local porting changes, so we weren't
sure it wasn't our problem until we checked the Solaris/OpenLook version, and
also backed out the 1.1.5K changes in our version.

So far, we have not found any problems other than image loading. We're also
seeing some issues with HotJava, but we're not sure yet whether these are
caused by our port or the new release. On the OpenLook system, it shows
behaviour similar to the image loading apps - initially blank blue screen, but
then shows the image when resized.

I can provide a small test case via ftp, or we can test things here if you send
the new version (or even just the source diff, we can apply it to our sources).
The test case is available via anonymous ftp at:

ftp://www.sgi.com/private/javasoft/imgbug.tar

un-tar the contents, then run

java DispImgApp

It should display two windows, each with the famouse "lena" image.

The Caffeinemark is a toy Java benchmark, obtainable from

http://www.webfayre.com

Two of the benchmarks involve image display - image and graphics - both of
these fail on irix/mwm and Solaris/OpenLook.

As soon as you've verified the fix (or even before), let us know where to get
the updated sources (if it is just a small change, a context diff is fine)
