STS 4.6.2 and Eclipse 2020-06 RC1: FrameworkEvent ERROR

[thokuest]

Since Eclipse 2020-06 is due this month I thought it's time to give it a try. So I downloaded the Eclipse IDE for Enterprise Java Developers 2020-06 RC1, started with an empty workspace and installed STS with all features via Marketplace client. The installation went smoothly without any issues. However, after a restart I observed that none of its features seem to be active. The error log reads:

Hey @thokuest, thanks a lot for reporting this. I can reproduce this issue using the latest Eclipse 2020-06 RC builds and after installing the STS 4.6.2 release.

The good news here is that this is already fixed for the upcoming 4.7.0 release. If you want to give the nightly CI build a try, feel free to install it from here:

https://dist.springsource.com/snapshot/TOOLS/sts4/nightly/e4.16

In this case, I would recommend to select the features from the update site manually, as described here: https://github.com/spring-projects/sts4/wiki/Installation#install-spring-tools-4-into-an-existing-eclipse-via-a-p2-repo

Or grab a ready-to-use distribution build from here:
http://dist.springsource.com/snapshot/STS4/nightly-distributions.html

Hope this helps and thanks for reporting this as early feedback for the upcoming release. Much appreciated.
