The "generate hashCode() and equals()" Source action logs a NullPointerException instead of opening the dialog if (1) the class has an inner class and (2) a package-info.java file exists in the same package.

Here is the exception stack trace:

Reproducible: Always

Steps to Reproduce:
1. Create a new package "foo"
2. Create a package-info.java file in this package. The file needs only contain the package declaration.
3. Create a class file "Foo.java" in the package with this content:
package foo;

public class Foo {

	private static class Bar {
	}

	private String baz;

}

4. Select "Source > Generate hashCode() and equals()" from the context menu.

Instead of showing the dialog, the exception is added to the error log.
