1. jsf-impl.jar and jsf-api.jar
svn downloads glassfish-jsf-1_2_08-0jpp_ep1_2_el5
zip uses glassfish-jsf-1_2_08-0jpp_ep1_3_el4

2. applet.jar and jfreechart.jar
svn adds to applet.jar the jfreechart-1_0_9-1jpp_ep1_2_el4 library
zip adds to applet.jar the jfreechart-1_0_9-1jpp_ep1_3_el4 library

3. activtion.jar
svn downloads glassfish-jaf-1_1_0-0jpp_ep1_5
zip uses glassfish-jaf-1_1_0-0jpp_ep1_12_el4

4. mail.jar
svn downloads glassfish-javamail-1_4_0-0jpp_ep1_5
zip uses glassfish-javamail-1_4_0-0jpp_ep1_10_el4

5. hibernate-entitymanager.jar
version used in svn is 3.2.1.GA-brew
version used in src is 3.2.1.GA_CP03-brew

6. jbossmq.jar
there is a diff in TxManager.java, the zip distro uses an older version(69738) than the svn(76000)

For 1 to 5, can't we use(download) the same versions of all thirdparty jars when building the zip distro?
6 looks bad
