Thank you Mark, it solve this problem.

The option --enable-default-toolkit=gnu.java.awt.peer.x.XToolkit is
needed with escher lib because if the parameter enable-default-toolkit
is not set , it will use gnu.java.awt.peer.gtk.GtkToolkit by default
(compile with GTK support) (Source part "dnl Default AWT toolkit" in
http://cvs.savannah.gnu.org/viewvc/classpath/configure.ac?revision=1.249&root=classpath&view=markup
)
