I've got some problems in understanding which are the 'fases' of an OSGi bundle
(a plugin). The keywords that are not clear are:
a. INSTALLED
b. STARTED
c. ACTIVATED
For example, when you 'start' the workbench plugin (org.eclipse.ui.workbench) is
it activated? It doesn't seem to me, because if you then 'start' the jdt.ui
plugin (org.eclipse.jdt.ui) it spits out an error () which resolves to the
method getWorkbench() of the class PlatformUI that happens when the workspaces
is not yet ... 'activated'?
All I'm trying to do is loading the org.eclipse.jdt.ui plugin at eclipse start,
editing the config.ini and adding these entries in the osgi.bundles:
org.eclipse.ui.workbench@4:start
org.eclipse.jdt.ui@4:start
I'd really appreciate some clarifications on these points as they're not so
clear in my mind! Also some links to good documentation of the Eclipse
start-level are really welcome! (Or if someone is so kind to give me some
explanations about them, too!)
Thank you in advance

Can you say why you are trying to do this? In general you do not have
to manually start bundles in Eclipse. Most/many have the
Eclipse-LazyStart: true
header in their manifest. This means that Equinox will start them as
needed where "needed" is defined as on class load.
