Eclipse sets that by default.

I understand that by default the warning is shown, but only if Eclipse thinks it cannot see the line number attributes. And I have that enabled. So that's what I meant to ask: Why is Eclipse showing this warning even if everything should work and seems to work - it seems that showing the warning is simply wrong in this case.

I have set a breakpoint to MemberService.listAllMembers() (line 72).
I don't have to click the "List Members" button no matter whether the "Warn when unable to install breakpoint..." checkbox is checked or not.
Could you try again in a new workspace?

I saw your screencast and I believed you even without it :) But still, in my case the breakpoint is only hit if I click the button on the web page. And now I can see why. For some reason I always get the mobile version of the page, so the list of members isn't shown and the breakpoint isn't triggered.

> I am unable to get breakpoints to work for a html5 project running on WildFly.
> I tried to verify JBIDE-20804 so I created the html5 project from central, set a breakpoint in MemberService.listAllMembers() (line 72) and then selected Debug on server -> WildFly. The server was started in debugging mode and the project started deploying, but then I got an error:
> Unable to install breakpoint in org.jboss.tools.example.html5.rest.MemberService$$$view3 due to missing line number attributes. Modify compiler options to generate line number attributes.
> Reason: Absent Line Number Information
> !breakpoint-error.png!
> I checked and this option was checked in Preferences -> Java -> Compiler. Also, I even checked the project settings (.settings/org.eclipse.jdt.core.prefs) and it has:
> org.eclipse.jdt.core.compiler.debug.lineNumber=generate
> This happened to me on Mac with WildFly 8, 9 and 10. And psrna checked this for me on Linux and the result was the same.
> I'm not really sure which component this should belong to, it looks like an upstream issue.
