Java updates on linux can be weird. We stopped automatic java package 
updates on our CentOS shibboleth server for a while because the java 
software location was based on the package version so moved when java was 
updated - the update process tried to copy over the relevant configuration 
files but they weren't where the running shibboleth process expected them 
and things broke. We haven't seen the problem since updating to java 11 
and a later version of shibboleth.
