I want to place a breakpoint in com.sun.jndi.ldap.LdapCtx to see how it works, however, my program is running with Java 11 and this class is invisible to Eclipse. How to configure the project so this class can be opened with the "Open Type" dialog? Is it necessary to convert the project into modular?
I've tried in project properties "Java Build Path" -> "Module Dependencies" -> java.naming -> "Configured details" -> "Expose Package...":
I tried both "exports" and "opens", but it doesn't let me actually view the classes inside.

In the preference Java > Appearance > Type Filters you have to uncheck the filter com.sun.* in order to be able to open com.sun.jndi.ldap.LdapCtx e.g. via Open Type (Ctrl+Shift+T).
