authn/Shibcas flow An I/O Exception occurred resolving the flow location pattern '/**/*-flow.xml

[Jehan Procaccia]

Hello

to start well the new year, I upgraded my IDP to 3.4.2 , it worked fine 
until I added the authn/Shibcas AuthenticationFlow .

When I start the IDP logs complains about an  "/I/O //Exception occurred 
resolving the flow location pattern '/**/*-flow.xml'/"

I read about that kind of error /"I/O //Exception... //location pattern 
'/**/*-flow.xml'" /on :

https://wiki.shibboleth.net/confluence/display/DEV/2018-07-20

setting an idp.home (althought it is install in default path) in 
/var/lib/tomcat/webapps/idp/WEB-INF/web.xml

<context-param>
         <param-name>idp.home</param-name>
         <param-value>/opt/shibboleth-idp</param-value>
         </context-param>

did not solved the issue .

What else can be done, what is the problem ?

Thanks .
