dev build from Dec 8, JDK 1.6.0_b62

After some editing of JSP files I close them all and closed the project but
there are still 35 instances of
org.netbeans.modules.web.jspparser_ext.WebAppParseSupport$ParserClassLoader
referenced from log factory of commons logging -

Static reference from org.apache.commons.logging.LogFactory.factories (from
class org.apache.commons.logging.LogFactory) :
--> java.util.Hashtable@0x8805d6a8 (40 bytes) (field table:)
--> [Ljava.util.Hashtable$Entry;@0x8872f968 (196 bytes) (Element 42 of
[Ljava.util.Hashtable$Entry;@0x8872f968:)
--> java.util.Hashtable$Entry@0x889e2af0 (24 bytes) (field key:)
-->
org.netbeans.modules.web.jspparser_ext.WebAppParseSupport$ParserClassLoader@0x889e4930
(67 bytes)

I am not clear how dangerous it is. At least there are 0 loaded classes so we do
not fill perm gen but still we are leaking in Java heap.
