I have a DocBook document containing 750 BW JPG photos, 300x450 pixels each. When I open this document in XXE (Linux Fedora Core 5, Java 1.5), then XXE loads the DocBook file, verifies its validity, and starts loading photos. System meters indicate "normal" activity, but after some time the situation changes, the CPU load reaches 100% and stays there forever.
My suspect was insufficient memory, even if I would prefer e.g. a message box to indicate that, rather than a neverending and uninterruptible operation. So I changed the default memory configuration from 128MB to 256MB and the same document loads successfully. Everything is fine, up to now. But when I close this document and open it again, I end up with the 100% CPU load and neverending operation again. The same happens when I press Ctrl-L on already opened document. It's clear to me that not everything in Java is under your control. It's also clear that a document containing so many photos is rather non-standard. On the other hand, having the document closed, I would expect all the image objects released, so the document re-opening should succeed again. Thank you Tomas Klinkovsky Czech Republic
