OSXでthe trustAnchors parameter must be non-emptyって出る

しばらく放置してたプログラムの開発を再開した。開発環境はMBP。OSX Mavericks。

で、起動したら、ある箇所で以下のようなExceptionが発生。

java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

ぐぐってみたら、JREの証明書がなんたらかんたら、と。詳細は省略するけど、Javaをインストールすれば（orし直せば）OK。MavericksではJavaがインストールされないの？

Java 6なら、Appleのサイトからダウンロード
Java 7なら、Oracleのサイトからダウンロード(JRE, JDK)
