An issue with applications running on IBM systems failing with a segmentation fault has been corrected in this release of JBoss EAP 6.
The crashes were caused by NIO implementations in IBM JDKs that are optimized for usage on IBM operating systems. The I/O layer in JBoss EAP attempts to detect and utilize these implementations. However on some operating systems (like IBM-I) these implementations cause a segfault.
In this release of the product, these operating systems are detected and safe fall-backs are utilized. This resolves the segmentation fault issue and the application server no longer crashes unexpectedly.
