Jeff McAffer, https://bugs.eclipse.org/bugs/show_bug.cgi?id=166011:
+
There are tools and facilities
+
available to better understand the startup sequence.  See
+
  [http://www.eclipse.org/eclipse/platform-core/downloads.php  Download Core Tools]
+
Using the core tools you can see exactly what causes each bundle to be started,
+
you can find out what causes each class to be loaded, etc etc.
+
 
+
Consists of three .jar files,
+
# org.eclipse.core.resources.spysupport
+
# org.eclipse.core.tools.resources
+
# org.eclipse.core.tools
+
 
+
To enable need to run eclipse with -debug <option file path>
+
 
+
Here is the Nov 2006 .options file [[CoreToolsOptionsExampleFile]]

===Adding 3rd Party Jar files===
+
 
+
Option 1: turn the jars into plugins
+
 
+
Use New>Project>Plug-in Development>Plug-in from existing JAR archive. That will turn one or more jar files into a single jar plugin. For something like log4j you can then set up Buddy-Classloading, etc.
+
 
+
Before 3.2.1, you need to add to the build.properties.  See [https://bugs.eclipse.org/bugs/show_bug.cgi?id=146042 Bug 146042 RCP export has problems with required plug-ins]
+
 
+
Option 2: include the jars in a plugin
+
 
+
# Use Import>File System to import the jar files into your plugin project, say in the <project>/lib directory.
+
# Use "Add..." to add the jars to the classpath section of the PDE Editor>Runtime tab.
+
# Use "New..." to add "." library back (with no quotes, of course).
+
# Make sure your binary build exports the new jar files on the PDE Editor>Build tab.
+
# Save
+
# On the project, use the popup menu>PDE Tools>Update Classpath to correctly add the jars to the eclipse project classpath.
+
# Export any packages that you need to using the PDE Editor>Runtime tab
+
# Save
+
 
+

It talks about how adding a 3rd party jar removes the default "." classpath, and the need to add it back.
+
 
+
Also, eclipse can handle jars within jars.  It expands them into a temporary location during runtime.
