Hi, People using Rawhide java-1.4.2-gcj-compat will have noticed that rebuild-gcj-db and aot-compile-rpm get deleted when upgrading from <= 1.4.2.0-40jpp_51rh to >= 1.4.2.0-40jpp_52rh. This was caused by a bug in "update-alternatives --install" where it would remove filenames that no longer appeared in the alternatives database: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=173685 Bill Nottingham has built into Rawhide chkconfig-1.3.24-1, which I confirmed fixes the bug. In the meantime you can work around the problem by --force reinstalling java-1.4.2-gcj-compat >= 1.4.2.0-40jpp_52rh and java-1.4.2-gcj-compat-devel >= 1.4.2.0-40jpp_52rh from your yum cache. Tom
