 /**
 22  
  * <code>WildcardFilter</code> is used to match Strings against wildcards. It
 23  
  * performs matches with "*", i.e. "jms.events.*" would catch "jms.events.customer"
 24  
  * and "jms.events.receipts". This filter accepts a comma-separated list of patterns,
 25  
  * so more than one filter pattern can be matched for a given argument:
 26  
  * "jms.events.*, jms.actions.*" will match "jms.events.system" and "jms.actions" but
 27  
  * not "jms.queue".
