Description Sander Stevens 2005-05-10 14:33:52 UTC 
I am using internal build 20050508.

During startup I get the following error:

2005/05/09 13:41:20 INFO  - jmeter.gui.util.MenuFactory: Could not instantiate

Solution is to add the mail.jar and activation.jar to the jmer bin folder. But
this shouldn't happen.

I've committed some changes to CVS HEAD to catch and log such errors separately.

If the mail jars are missing, JMeter now logs a shorter warning message.

[By the way, the jars should be put into the lib rather than the bin directory.]
