/**
 * This test checks that the JDWP command <code>FieldsWithGeneric</code>
 * from the <code>ReferenceType</code> command set returns generic signature
 * information properly.<br>
 * Debuggee part of the test contains several tested fields. Some of them
 * are generic including the inherited fields. Debugger part obtains
 * information for each field in a reference type of a tested class.
 * Proper generic signature should be returned for the generic fields, or
 * an empty string for non-generic ones. Information for the inherited
 * fields should not be returned.
