I managed to install EJBCA with “ant install” on EAP 6.4. Later I realized that I encountered the problem when I tried to install it on EAP 6.4.19. In order to install it on EAP 6.4.19 I had to change "/interfaces=/interface=" to "/interface=" otherwise I got exception "Can't reset to root in the middle of the path @12". This exception was implemented in Wildfly by the following commit 

https://github.com/wildfly/wildfly-core/commit/3d5111dd6bd32203dd7c41cd2403b994a0b96d08#diff-93f2c59d2b103af3e5ebebeabf84b45b 

in order to fix the following bug 

https://issues.jboss.org/browse/WFCORE-285 

I guess this bug fix has been transferred to EAP somewhere between 6.4.1 and 6.4.19. 

I can trigger this bug (as described in the link above) in EAP 6.4 but not in EAP 6.4.19, so I think this fix also catches the incorrect commands in “jboss.xml”, because if I understand it correctly the command 

/interfaces=/interface=… 

will try to reset the root of the path which the bug fix prevents. 

On EAP 6.4 I can run command 

/hasthage=/interface=… 

with correct result. Probably because it will skip “/hasthage=” when the root is set to “/interface=…” 

for example 

/hasthage=/interface=httpspub:add(inet-address="0.0.0.0") 

will give same result as 

/interface=httpspub:add(inet-address="0.0.0.0") 
on EAP 6.4 but on 6.4.19 it will give 

“Can't reset to root in the middle of the path @10”
