Is there an alternative to the EAP 5.1.2 Java 7 patches installer?

Issue

• Is there an alternative to EAP 5.1.2 patch installer for JDK 1.7
• I have tried to install the Java 7 patch for EAP 5.1.2 [1]. Our JBoss EAP is customized and the patch installation fails.
  We would like install the Java 7 patches manually without installer. In the readme.txt of [1] we have found the patch list. Where can we download the individual patch files? Is it possible to install the patches manually?
