Issue

• Getting a NullPointerException when trying to run the JDK 7 patch installer (JBPAPP-8693).

Exception in thread "main" java.lang.NullPointerException

• We need to run our EAP 5.1.2 in our solaris machine with java 1.8. We need to download JBPAPP-8693 , but when I arrive to the download page I can´t download this patch.
