== Why is this an issue?

According to the Java Language Specification:


____
Unnamed packages are provided by the Java platform principally for convenience when developing small or temporary applications or when just beginning development.

____

To enforce this best practice, classes located in default package can no longer be accessed from named ones since Java 1.4.


=== Noncompliant code example

[source,java]
----
public class MyClass { /* ... */ }

=== Compliant solution

[source,java]

public class MyClass{ /* ... */ }
