Chapter 3. Unsupported features and deprecated features 3.1. Unsupported features Support for some technologies is removed due to the high maintenance cost, low community interest, and better alternative solutions. The following features are not supported in JBoss EAP XP 4.0.0: Platforms and features Oracle Solaris JBoss EAP deprecated the following platforms in version 7.1. These platforms are not tested in JBoss EAP 7.4. Oracle Solaris on x86_64 Oracle Solaris on SPARCv9 JBoss EAP 7.4 does not include the WildFly SSL natives for these platforms. As a result, SSL operations in Oracle Solaris platforms might be slower than they were on versions of JBoss EAP. Java Development Kits Since JBoss EAP XP 4.0.0, Java Development Kit 8 (JDK 8) is now unsupported. Note JBoss EAP XP 3.0.0 will be supported for 3 months or 2 cumulative patches after JBoss EAP XP 4.0.0 is released. RESTEasy parameters RESTEasy provides a Servlet 3.0 ServletContainerInitializer integration interface that performs an automatic scan of resources and providers for a servlet. Containers can use this integration interface to start an application. Therefore, use of the following RESTEasy parameters is no longer supported: resteasy.scan resteasy.scan.providers resteasy.scan.resources Red Hat JBoss Operations Network Using Red Hat JBoss Operations Network (JON) for JBoss EAP management is deprecated since JBoss EAP version 7.2. For JBoss EAP 7.4, support for Red Hat JON for JBoss EAP management is deprecated. MS SQL Server 2017 MS SQL Server 2017 is not supported in JBoss EAP 7.4.
