How about adding something like

   permission java.io.FilePermission
   "${catalina.base}${file.separator}webapps/-", "read";

to the block starting with

   grant codeBase "file:${catalina.home}/bin/tomcat-juli.jar"

The security manager should mainly protect you somehow against malicious
 webapp code. So giving those permissions to tomcat-juli doesn't seem to
be to big a problem. You can even narrow that down to giving it only to
the class org.apache.juli.ClassLoaderLogManager.

I don't know how the file system layout of the webapps for all your
vhosts looks like, but wouldn't something like this be a good compromise
for 5.5.27?

Regards,

Rainer
