Mixed-case Java package name not resolved

Description

Referencing a Java class with a mixed-case package name, e.g. Java::mixed.Case.Example, fails. Although a mixed-case package violates the Java naming standard, it is legal. The use case is integration with existing Java code that cannot be modified.

Test case:

1. Make a jar file with the trivial Java class:

package mixed.Case;

public class Example
{
}

2. require the jar file

3. Java::mixed.Case.Example #=> NameError
