Upgrading Java from 7u161 to 7u171 prevents JBoss AS 7.1.1.Final from starting. I know JBoss AS 7.1.1 is EOL but for compatibility reasons, we still need to run this version.
Very early in the startup, a NullPointerException occurs in some JBoss method. Following is the exception:
Exception in thread "main" javax.xml.parsers.FactoryConfigurationError: Provider __redirected.__SAXParserFactory could not be instantiated: java.lang.NullPointerException
[...]
Caused by: java.lang.NullPointerException
at __redirected.__RedirectedUtils.loadProvider(__RedirectedUtils.java:94)
The full stack is here.
回答1:
Could you try upgrading jboss-modules.jar (found in the root folder of the jboss-as binary distribution) to 1.1.5.GA?
The version of jboss-modules which comes with jboss-7.1.1.Final is 1.1.1.GA and it has a few issues with initialisation order and multiple-initialisation which could be causing the issue.
回答2:
Are you sure you are using a jdk 1.7?
This issue can happen when you try to start Jboss with java version > 1.7, try to check your JDK installation folder.

Environment as Follow: Jboss: JBoss AS 7.1.1.Final, OS: Ubuntu 16.04.1, and, java: 1.8.0_181.
I have downloaded jboss-modules-1.1.5.GA.jar and replace to jboss-modules.jar at JBOSS_HOME. It worked for me.

I had same issue on my Production Server
My Environment :-
JBoss AS 7.1.1.Final
Red Hat Enterprise Linux 6.5
java: 1.7.0_181
Even i had jboss-modules.jar which comes by default in JBoss AS 7.1.1.Final ,
So i downloaded jboss-modules-1.1.5.GA.jar , renamed it as jboss-modules.jar
and replaced it with original jboss-modules.jar.
