Springframework JavaMailSender doesn't work anymore on OpenJDK1.7
===

I've a EmailService Class like this: 

    package com.helios.service.mail;

    import java.util.ArrayList;
    import java.util.List;

    import javax.mail.MessagingException;
    import javax.mail.NoSuchProviderException;
    import javax.mail.internet.AddressException;
    import javax.mail.internet.MimeMessage;

    import org.apache.log4j.Logger;
    import org.springframework.stereotype.Service;

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mail.MailException;
    import org.springframework.mail.javamail.MimeMessageHelper;
    import org.springframework.mail.javamail.JavaMailSender;

    import scala.actors.threadpool.Arrays;
    import com.helios.util.PropertiesUtil;

    /**
     * The e-mail service contains all you need in order to send E-Mails 
     * successfully
     */
    @Service
    public class EmailService
    {
    	// ------------------------------------------------------------------------
    	// members
	// ------------------------------------------------------------------------

	// log4j...
	static final Logger logger = Logger.getLogger(EmailService.class);
	
	@Autowired
    private JavaMailSender mailSender;
	
	// ------------------------------------------------------------------------
	// public usage
	// ------------------------------------------------------------------------
	
	/**
	 * Send an Email the cool way!
	 * @param recipients
	 * @param subject
	 * @param text
	 * @param html
	 */
	public void sendEmail(List<String> recipients,String subject,
			String text,boolean html)
		throws NoSuchProviderException,AddressException,MessagingException {
		
		try {
			MimeMessage mimeMessage = mailSender.createMimeMessage();
			MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage);
			messageHelper.setFrom(PropertiesUtil.getProperty("mail.defaultsender"));
			messageHelper.setTo(recipients.toArray(new String[recipients.size()]));
			messageHelper.setSubject(subject);
			messageHelper.setText(text, html);
			mailSender.send(mimeMessage);
		}
		catch (MailException ex) {
			logger.error("Fail: "+ex.getMessage());
		}
		
	}
	// ------------------------------------------------------------------------
	// private usage
	// ------------------------------------------------------------------------

	
	// ------------------------------------------------------------------------
	// GETTER & SETTER
	// ------------------------------------------------------------------------
    }

A bean is used to configure the mailSender to send trough Amazon SES

      <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    	<property name="host" value="email-smtp.us-east-1.amazonaws.com" />
    	<property name="port" value="465" />
    	<property name="protocol" value="smtps" />
    	<property name="username" value="..." />
    	<property name="password" value="..." />
    	<property name="javaMailProperties">
        	<props>
            	<prop key="mail.smtps.auth">true</prop>
            	<prop key="mail.smtp.ssl.enable">true</prop>
            	<prop key="mail.transport.protocol">smtps</prop>
            	<prop key="mail.debug">true</prop>
        	</props>
    	</property>
	</bean>

Now, if i run the sendEmail method under JDK1.6 it will work fine. If i run absolutly same code on 1.7 it won't work. 

I can't find out where the problem is. Do you have any idea?

Thanks!
