Loading tcnative-1 throws: java.lang.UnsatisfiedLinkError: no tcnative-1 in java.library.path

Issue

We are ionstalling the native libraries (jboss-eap-native-6.1.1-win6.x86_64) on JBoss EAP 6.1 to improve the performance of our environment.
It seems to work properly but we find an error related to tcnative-1 library:
