Related to: #1706

In CI runs (at least in GitHub Actions), we face Edge browser initialization randomly taking a long time. For SWT browser tests, the timeout value is currently increased, but for tests in Platform UI that create a browser it is obviously not.
I thought about trying to limit the timeout to GitHub Actions environments, but I intended to do that in the tests and not in productive code. But that would mean that we have to configure all tests that may use an Edge browser...
Let's see what we can do for the issue directly in SWT first.

[fedejeanne]

Do we plan to do something about this in the coming days/weeks? The timeout of 90 seconds (7ad097a) seems to be enough.

[HeikoKlare]

It would be good to do something about this. The timeout of 90 seconds is only applied to SWT browser tests. All other consumers use the default timeout (5 seconds) if not specified otherwise. This results in the posted issue in SWT consumers tests (like in Platform UI but potentially also in other RCP extension or RCP product builds like ours) .

[fedejeanne]

So what you're saying is:

1. It's OK if tests have a long timeout
2. It's not OK that currently only the browser tests have a long timeout
3. We should not change the timeout in production code

So we should address point Nr. 2.

Correct?

[HeikoKlare]

Well, it would of course be best to address point 1, as it's still questionable that some operations take so long during test execution.

[travkin79]

While working on an Eclipse plug-in using the Eclipse internal browser, I faced a very similar issue. But in my case, there are no automated tests involved. I got the following stacktrace while trying to open a URL in the internal web browser.

Since the line numbers in my stacktrace and in the stacktrace reported by @jukzi differ, I'm not sure if the issues are related. What do you think?

The relevant code used for creating the browser is the following:

IWebBrowser webBrowser = PlatformUI.getWorkbench().getBrowserSupport().createBrowser(
	IWorkbenchBrowserSupport.LOCATION_BAR
	| IWorkbenchBrowserSupport.NAVIGATION_BAR
	| IWorkbenchBrowserSupport.STATUS
	| IWorkbenchBrowserSupport.AS_VIEW,
	"com.some.company.fluentmark.browser.id",
	"FluentMark browser",
	"Browser instance used by Fluentmark to open any exernal link");
webBrowser.openURL(url);

The last release in which this line information fits is the 2025-03 release:

org.eclipse.swt.browser.Edge.createTimeOutException(Edge.java:525)

A bunch of problems with Edge have been fixed since then, so you should reevaluate with the latest Eclipse release or even I-Build.

[travkin79]

Thank you, @HeikoKlare, Eclipse 2025-03 is the target that I'm currently using for testing. I'll test with the latest Eclipse version, too.

I tested the same code with Eclipse 2025-12 (latest release). I have pretty much the same result, other line numbers in the stacktrace. I'll also try to create a target based on 2026-03 and re-test, but I don't expect any changes.

I reevaluated with Eclipse 2026-03 (based on https://download.eclipse.org/staging/2026-03/, org.eclipse.platform.feature.group vers. 4.39.0.v20260219-0810). I get the same results.
