JDK-4764639 - Errors when loading PNG/GIF images from compressed JAR files
Description
on solaris 5.7:

tested using latest Mantis promoted build.

When reading a PNG image via http, sometimes IIOException is thrown, sometimes it doesn't.

The following  testcase is attached.

I tried on WinNT and XP home, cannot reproduce the problem.

tried without the -Xmx500m -Xms100m arguments, same problem.  customer used the specific heap sizes because they said they need it for their application.  they need to load PNG images that are 40+mb in sizes.

However it is not reproducible on current devel build from Tiger workspace. On other hand observed symtopms are not stable - in some cases i see "javax.imageio.IIOException: Unknown row filter type" error in others - "java.util.zip.ZipException: incomplete literal/length tree". Therefore it looks like the problem is caused by broken input stream for image. Described problem occurs only when we do not use ImageIO cache (i.e. ImageIO.setUseCache(false);) Therefore problem is related to MemoryCacheImageInputStream. Similar problem was recently fixed as part of 4764639. Fix is integrated into current workspace and this is why I can not reproduce problem reported here with devel build. I also checked that rollback of patch for 4764639 resurrect the problem. So I conclude this bug is duplicate of 4764639. ======================================================================

WORK AROUND customer suggested work around: reload the image again until it loads properly and does not throw exception.
