Any experience with JDeveloper?

F18, JDev11123. Installed JDeveloper with no problem. Now I get this message when I try to start it:

Exception in thread "main" java.lang.UnsatisfiedLinkError: [MW_HOME]/jdk160_24/jre/lib/i386/xawt/libmawt.so: libXtst.so.6: cannot open shared object file: No such file or directory

... where [MW_HOME] is default location. Any experience here how to solve this?
