spring-boot fatjar: java.lang.ClassCastException: class com.sun.jndi.ldap.LdapCtx cannot be cast to class org.springframework.ldap.core.DirContextOperations (com.sun.jndi.ldap.LdapCtx is in module java.naming of loader 'bootstrap'; #20666

I have an app which runs fine in the IDE/cmdline, but through the fat-jar it fails with the following stacktrace - note the mention on "loader bootstrap" - since it works outside of the fat-jar I assume this has something to do with the fat-jar special loader.

I'm on spring-boot 2.2.5 and JDK14 (AdoptOpenJDK).

Caused by: java.lang.ClassCastException: class com.sun.jndi.ldap.LdapCtx cannot be cast to class org.springframework.ldap.core.DirContextOperations (com.sun.jndi.ldap.LdapCtx is in module java.naming of loader 'bootstrap'; org.springframework.ldap.core.DirContextOperations is in unnamed module of loader org.springframework.boot.loader.LaunchedURLClassLoader @1698c449)

See updated spring ldap issue and https://stackoverflow.com/questions/45742638/classcastexception-while-searching-for-ldap-user - this is not a boot-issue.
