Annoying error message on every eclipse startup if CF destination is not reachable

[MahatmaFatalError]

Expected Behavior

The error popup (see Current Behavior) should not appear. Having it in the error log and in the tooltip is enough.

From the error log:

Current Behavior

Error message pops up with every start of eclipse.

Context
To be honest, the message in the error popup doesn't really describe where it comes from and which action or component is related to it. So it is just annoying.

eclipse.buildId=4.12.0.202109130635

@MahatmaFatalError This has been fixed. Can you try a latest CI build from here and give us feedback on this quickly? http://dist.springsource.com/snapshot/STS4/nightly-distributions.html

Since we are approaching the 4.12.1 release, I would need some feedback on this very quickly... ;-)

[MahatmaFatalError]

@martinlippert Sorry, I cannot reproduce this quickly since the issue originated from an expired auth token. Since I cannot save an invalid authentication, I will have to wait until the token expires and check then again.

BTW, just stumbled over Unhandled event loop exception with spring-tool-suite-4-4.12.1.CI-B2628-e4.21.0-macosx.cocoa.x86_64
