HTL sites not displaying anymore jdk.nashorn.internal...

Running AEM 6.5.4
Java(TM) SE Runtime Environment(build 11.0.5+10-LTS)

Have you solved this issue?  We have no problem when we restart AEM, all things seem to work fine.  What appears to be out of the blue, all HTL related pages stop displaying with this same error.  If we restart, we are fine again.
