The EPEL 7 SRPM for jboss-jstl-1.2-api 
https://dl.fedoraproject.org/pub/epel/7/SRPMS/j/jboss-jstl-1.2-api-1.0.3-10.el7.src.rpm
does not build correctly in Mock on s390x. 

The extension xml.jar shipped with IBM JDK already contains a version of class "org.apache.xpath.res.XPATHErrorResources", which is incompatible with this SRPM. Thus building this project would fail due to "symbol cannot be found" compilation error. 

We can fix this issue by specifying openJDK (instead of java-devel) as the build requirement in spec file for now.

We have found a workaround to fix this issue.

We add 2 maven plugins:
1. copying xalan-j2.jar to a directory under build directory 
2. use -Djava.endorsed.dirs option to endorse the directory which contains the copied jar.

After applying these changes, jboss-jstl can be built correctly on s390x.

Ideally, it would be better to endorse /usr/share/java instead, as this is where xalan-j2.jar originally located in Mock. 

However, endorsing that directory will create another conflict. To avoid this conflict, xalan-j2.jar is copied to a different directory and that directory is endorsed instead.

patch to endorse xalan-j2.jar on IBM JDK
