ClassIndex must check for NoClassDefFoundError also

[ptahchiev]

At the moment the ClassIndex is only checking for a ClassNotFoundException during class loading: https://github.com/atteo/classindex/blob/master/classindex/src/main/java/org/atteo/classindex/ClassIndex.java#L404-L406

However, I believe it should be checking also for NoClassDefFoundError (see image):

I have a maven project with two modules:

• moduleA
• moduleB defines module A as optional dependency.

Then the client has the option to chose which combination of modules to add in their classpath - moduleA, moduleB, both modules or none of the modules.

If the customer selects moduleB only then I try to find subclasses:

ClassFilter.only().topLevel().from(ClassIndex.getSubclasses(AbstractEntityDefinition.class))

and then it fails with NoClassDefFoundError because the index file in moduleB was created when moduleA was there during compile time but is missing at runtime now.

Any idea when the next release will be out?

I've released version 3.9 just a minute ago. Should appear in Maven Central in about a day.
