Gary Gregory commented on LOG4J2-1051:
--------------------------------------

Ah, I see this in Loader:

{code:java}
    static {
        final SecurityManager sm = System.getSecurityManager();
        if (sm != null) {
            sm.checkPermission(new RuntimePermission("getStackTrace"));
            sm.checkPermission(new ReflectPermission("suppressAccessChecks"));
        }
    }
{code}

and I bet that {{checkPermission}} throws a {{SecurityException}} and we do not see it.
