/**
 * {@link ServiceName}配列型のPropertyEditorクラス。<p>
 * "[サービスが登録されるマネージャ名]#[サービス名]"の文字列を改行区切りで複数指定した文字列を{@link ServiceName}型の配列オブジェクトに変換する。<br>
 * 最初と最後の空白と改行前後の空白はトリムされる。空白は、{@link java.lang.Character#isWhitespace(char)}で判定される。また、"&lt;!--"と"--&gt;"に囲まれた文字列はコメントと解釈され無視される。また、"${"と"}"に囲まれた文字列は、同名のシステムプロパティと置換される。<br>
 * <p>
 * 例：<br>
 * &nbsp;&nbsp;Manager1#Service1<br>
 * &nbsp;&nbsp;#Service2<br>
 * &nbsp;&nbsp;&lt;!--Manager1#Service3--&gt;<br>
 * &nbsp;&nbsp;Service4<br>
 * <br>
 * のような文字列が、{@link #setServiceManagerName(String)}で"Manager2"と設定してあれば、<br>
 * <br>
 * &nbsp;&nbsp;new ServiceName[]{<br>
 * &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;new ServiceName("Manager1", "Service1"),<br>
 * &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;new ServiceName("Manager2", "Service2"),<br>
 * &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;new ServiceName("Nimbus", "Service4")<br>
 * &nbsp;&nbsp;}<br>
 * <br>
 * のように変換される。<br>
 * 文字列からサービス名への変換方法は、{@link ServiceNameEditor}を参照。
