[platform-ui-dev] Question regarding bundle activation

Dear platform devs,


I just tried the following experiment to better understand how eclipse starts up:

I took a resent photon build as target platform and started a target workbench (I started the “org.eclipse.platform.ide” product). In the target workspace, I switched to the resource perspective, closed all JDT / PDE view and created a “General Project” with one open txt-file in it.

When I restart that target workbench with the debug/bundleTime tracing parameter of the org.eclipse.osgi bundle set to true I see that some JDT and PDE bundles are loaded

Why are these bundles loaded? They take about 1 second to activate on my machine. I would have expected that these bundles are not touched until I actively touch them.

Is there a way to find out why a bundle is activated?
