Could you try getting a code dump.

My guess is that you're encountering issues loading the embedded web browser. Can you try opening the internal web browser (Quick Access > "Web Browser" and select the "Internal Web Browser")? If that crashes too, there are some details in the SWT FAQ on diagnosing and solving the issues.

That said, Help > Help Contents for me actually opens a web browser.

Hi Brian,

I have attached the dump file on this comment.

And I follow your step: (Quick Access > "Web Browser" and select the "Internal Web Browser")

If I do not set the web location (defaule:empty page), the browser works will.

If I point the location to the Help Content Part. such as: http://127.0.0.1:39373/help/nav/15,
the Platform also crash.

If I set the 'org.eclipse.swt.browser.DefaultType=mozilla' property in config.ini, Eclipse Platfrom will open the outside browser, and then the planform also works well.

Can you try using a different URL instead of your local help on localhost, like www.eclipse.org? Does that crash? That will help isolate whether it's the SWT Browser crashing (my suspicion) or the Help system crashing (seems very unlikely to crash the JVM).

From the .logs it looks like SWT Browser crashing:

I'm not sure what version of version of RHEL you're using. You may well have buggy versions of GTK3 libraries. Perhaps you could try running with SWT_GTK3=0 in your environment (or launch Eclipse with "--launcher.GTK_version 2") and see if that helps.
