RCU/jdk/jre/lib/i386/xawt/libmawt.so: libXtst.so.6: cannot open shared object file: No such file or directory

I got this error while installing RCU on OEL6.

$ ./rcu
Exception in thread "main" java.lang.UnsatisfiedLinkError:

Cause: 
libXtst rpm for 32 bit is missing.

Fix:
Please check that the libXtst-xx.el6.i686.rpm (32 bit) installed.
rpm -qa |grep libXtst
If it is not installed the need to install:
rpm -ivh libXtst-xx.el6.i686.rpm
