Searching classes by access level in a project?

We've a rather large project (1 million+ lines of code in something like 25 modules) and are in the process of porting it from an old JBoss version to Wildfly.

Due to the new classloading system Wildfly uses, this means reorganising code across modules. As some classes have been marked package private/default in the past, which caused no problems at the time as JBoss used to load all jars inside the same classloader, these classes now are becoming inaccessible (even though they're in the same package as the classes calling them, but in a diffrent jar).

Compile time everything is fine, Maven and IntelliJ don't complain because of the package hierarchy.

But because of the specific way in which Wildfly handles classloading across jars, at runtime this gives some very nasty exceptions.

Caused by: java.lang.IllegalAccessError: tried to access class

and another few hundred lines...

Is there a way to show all classes in the project that are package private/default access?
