javaparser 3.24.4

https://github.com/javaparser/javaparser/releases/tag/javaparser-parent-3.24.3 seems to have breaking changes. This is tagged 3.24.3 but that release seems to have failed and a newer release 3.24.4 was made.

The xmlbeans build fails with this version. It appears some generated code appears in Java files whose name does match the name of the class (case sensitivity issues).

We could fix the tests so that the build succeeds but the question is would users who use XMLBeans also hit similar issues with their XSD to Java code generation?
