Doc Text:	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.	Story Points:	---

Description Brad Maxwell 2013-11-13 22:52:46 UTC

- Do not try to use optimized selector providers on OS/400 since that can cause a segfault
-  Do not specify SSL provider because IBM does not have this one 
- Do not recurse when old locking is in effect
