Disconnected in DBusConnection.getConnection

[Janne Kario]

dbus 1.2.1
dbus-java 2.5
machine is ARM
java vm is jamvm 1.5.1

For some reason calling Hello of org.freedesktop.DBus causes
connection to be disconnected. Sometimes I manage to get past the
DBusConnection.getConnection method but after that the subsequent dbus
call causes the connection to be disconnected. Any ideas? DBus seems
to be working because I can operate from the command line using
dbus-send. Python bindings also work.
