The application consists of more than 20 Jars. Each Jar is referenced by a corresponding resource JNLP file and could be verified with success except the only one, that contains a shared object library.

Using Java 1.8.0_73 (Java(TM) Web Start 11.73.2.02-fcs) ALL signed Jars could be verified with success and the application is running.

REGRESSION. Last worked in version 8u73
