javax.mail.Session is created before all properties are set

org.jbpm.process.workitem.email.SendHTML within jbpm-workitems/
Line 160-162 should come before "session = Session.getInstance(properties);"
if( connection.getStartTls() != null && connection.getStartTls() ) {
properties.put("mail.smtp.starttls.enable","true");
}
--> email task with tls authentication doesn't work
