java.lang.IllegalAccessError when I try to open the sitemap editor

[jm009]

When I click on the sitemap editor icon in the toolbar of /opencms/opencms/welcome/index.html, I get the exception below. This seems to happen for all other pages too.
I have opencms 8.5.2 running under Glassfish with postgresql.

I am not yet familiar with opencms, but what I can say is, that I can open the workplace, and the workplace looks good.

The problem seems to be, that Glassfish 4.0 already provides the com.google.common.collect.MapMaker class in a newer version, and that the servlet specification requires, that server provided classes should be used before application specific classes by default.

I solved the problem by adding a file glassfish-web.xml to /opt/glassfish4/glassfish/domains/domain1/applications/opencms/WEB-INF/
