private void runEarlyStartup(java.lang.Object executableExtension)

---

getExecutableExtension

private java.lang.Object getExecutableExtension(org.eclipse.core.runtime.IConfigurationElement element)
                                         throws org.eclipse.core.runtime.CoreException

In 3.0 the class attribute is a mandatory element of the startup element. However, 2.1 plugins should still be able to run if the compatibility bundle is loaded.

---

getPluginForCompatibility

private java.lang.Object getPluginForCompatibility()

If the compatiblity bundle is loaded, then return the plugin object for the extension on this runnable. Return null if the compatibility bundle is not loaded or the plugin object cannot be created.
