fwiw, when I run this with my own 4.0 build I get: opsy. gij ShowJPEGReader gnu.java.awt.peer.gtk.GtkToolkit@55c40 Exception in thread "main" java.util.NoSuchElementException at java.util.AbstractList$1.next() (/home/tromey/gnu/4.0/install/lib/libgcj.so.6.0.0) [ ... ] Is that normal? Should there be a next() here? That looks like correct output assuming we don't find any jpeg readers. AbstractList is returning an anonymous ListIterator, which is throwing an exception in next() because it is empty. So... why is it empty? Did you configure with the gtk peers? I'm hoping to find the gtk image reader in the list. Could you try "JPG" "jpeg" "jpg"? I'm going to do a clean rebuild of everything, since you don't seem to be having the same problem as me. This is a duplicate of libgcj/20693 in the GCC bugzilla database. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20693 HJ posted a libtool patch, and we need to apply it in order to build properly. I checked in an alternate fix to the 4.0 branch a few days ago. http://gcc.gnu.org/ml/java-patches/2005-q2/msg00136.html This should be fixed in rawhide as soon as jukub pulls the latest bits from FSF. This change is in libgcj-4.0.0-1. |

It should exist in the awt peer .so file. The really weird thing is that it doesn't, although it _does_ contain code for an anonymous inner class that it contains! $ nm -D /usr/lib/lib-gnu-java-awt-peer-gtk.so.6.0.0 | c++filt | grep GtkErrorImage 0006d258 T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::isConsumer(java::awt::image::ImageConsumer*) 0006d220 T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::addConsumer(java::awt::image::ImageConsumer*) 0006d290 T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::removeConsumer(java::awt::image::ImageConsumer*) 0006d2c8 T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::startProduction(java::awt::image::ImageConsumer*) 0006d38c T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::requestTopDownLeftRightResend(java::awt::image::ImageConsumer*) 000a3700 D gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::class$ 0006d1e0 T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::finit$() 0006d194 T gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage$1::GtkToolkit$GtkErrorImage$1(gnu::java::awt::peer::gtk::GtkToolkit$GtkErrorImage*) My FSF 4.0 branch build that I did myself doesn't have this problem. I tried replacing the /usr/lib peer library with my own build, and came across another instance of a missing inner private class: javax.imageio.ImageIO$ReaderFormatFilter.
