java.lang.UnsatisfiedLinkError: Native Library ... already loaded in another classloader in JBoss EAP

Issue

• We upgraded to jboss 5.1.0 recently. Our app has couple of wars projects with Lotus form.

• We get the below error on opening the forms. The issue is inconsistent. Please advice where and how I can set the classloader to load the dll (see log trace) just once.
