Run As/Debug As context menu in java source editor and package explorer does not show entries

[LorenzoBettini]

With Eclipse (Linux)

Version: 2024-03 M1 (4.31.0 M1)
Build id: 20240111-1612

and Eclipse Java Development Tools 3.19.400.v20240104-1800

the Run As/Debug As context menu in java source editor and package explorer does not show entries; at least, not in a usable way, see the screenshot:

On the contrary, the ones in the toolbar and in the "Run" menu work as expected.

please have a look in the "Error Log" view if you find a related exception

[LorenzoBettini]

@jukzi the error log doesn't show anything in that respect.

The terminal from where I started Eclipse shows (after using "Run As"):

*** BUG ***

Set a breakpoint on '_pixman_log_error' to debug

I don't think this is JDT problem, most likely GTK / SWT issue on HiDPI monitors / Wayland.
Please try to either use X11 or switch to "low" DPi and see if the problem disappears.
If not, please provide SWT/GTK config lines you can find in Help->About->Installation Details->Configuration.

[LorenzoBettini]

I'm on X11, not Wayland.
I'll try also lower DPI.
Concerning the config lines, is it enough to copy everything that "Configuration" provides if I type "gtk" in the search field?

[iloveeclipse]

No, please provide these entries that shown for SWT and for GTK from "*** System properties" and "*** System environment variables" sections

[LorenzoBettini]

@iloveeclipse I tried both with X11 and Wayland and I also switched to 100% HDPI (so, no scaling); the result is always the same, and so are the logged information in the terminal.

These are the entries you asked for:

Some updates: the problem appears only the first time you select the Run As/Debug As menu in the context menu: if you get back to Run As/Debug As (without closing the context menu) the entries appear and can be selected. Unfortunately, it happens again if you close the context menu and open it again. When the problem appears, I can quickly spot something like "Loading..." in the small submenu. So, I wonder if this issue is a consequence of this other issue: #1056

[jukzi]

@mickaelistria @fedejeanne can this issue relate to the changes in run menu? for example eclipse-platform/eclipse.platform#1005

[LorenzoBettini]

One new thing I noted (I'm pretty sure it wasn't there before) is that the context run menu now shows existing launch configurations associated to that file.

[mickaelistria]

@jukzi yes probably. @fedejeanne I suspect the issue is that the menu doesn't refresh its layout well and remains too small to show the entries.

[LorenzoBettini]

But, just for curiosity, am I the only one seeing this problem? By the way, I can see that in all my Linux installations. Not on mac m1, though.

[mickaelistria]

I noticed it yesterday on Linux as well. I think it's related to async computation of submenus/items which menu ignores when computing its size.
I see the same issue with async dynamic inputs in menus in LSP4E > Code Actions: the menu looks empty while is has some contents; here too, computation is async.

@fedejeanne pleae fix or revert

[LorenzoBettini]

Unpopular opinion: life is much better with blocking operations and without concurrency/asynchronicity... ;)

[LorenzoBettini]

Sorry for the ping, but this bug is critical concerning usability...

[mickaelistria]

@LorenzoBettini Can you please submit a fix or revert PR?

[LorenzoBettini]

@mickaelistria I think the original author should do the fix or, better, the revert of the PR. I don't know the internals of JDT; the original author should, and it should be a matter of minutes. For me, it would take ages...
I'm happy to help, but also time optimization is important ;)

[jukzi]

Please name the PR that causes the issue so that we can revert.

[mickaelistria]

I think the original author should do the fix or, better, the revert of the PR.

Sure, but in practice, this is not happening as you can see here. So someone else has to do the work.
The discussion has pointed to eclipse-platform/eclipse.platform#1005 , please consider trying to revert it locally to ensure if fixes your issue, and if it does, submit a PR. There is no need for any JDT expertise here, just plain Git and Eclipse PDE usage.

[LorenzoBettini]

@mickaelistria @fedejeanne can this issue relate to the changes in run menu? for example eclipse-platform/eclipse.platform#1005

@jukzi you mentioned the change

[jukzi]

@jukzi you mentioned the change

that was a guess... did you verify a revert of that helps?

[iloveeclipse]

I've just reported another issue related to this code, see eclipse-platform/eclipse.platform#1202.

I would propose to revert the two related commits as they both are part of same feature.

• eclipse-platform/eclipse.platform@494483e
• eclipse-platform/eclipse.platform.ui@771d0b4

[jukzi]

please do, when you know that they cause this issues. @fedejeanne had enough time to repsond.

[iloveeclipse]

@LorenzoBettini : please check next IBuild, I've reverted related commits.
At least eclipse-platform/eclipse.platform#1202 is fixed by that.

[LorenzoBettini]

@iloveeclipse I'm trying to use https://download.eclipse.org/eclipse/updates/4.31-I-builds/ for updating "platform", I guess the hopefully fixed version is org.eclipse.platform_4.31.0.v20240213-2236.jar

However, it refuses to update because of the conflict with the EPP package

However, I could update my TP and start a new Eclipse workbench. I see the problem went away in the started workbench!
So it looks like it is fixed now.

So it looks like it is fixed now.

Perfect, thanks for confirmation. Closing as duplicate of eclipse-platform/eclipse.platform#1202.

[fedejeanne]

Hello everyone,
I came back from a leave of several months just recently, hence the radio silence. Sorry to hear that my change brought some problems, thanks @LorenzoBettini for reporting it!

I've been looking into it and I couldn't find anything useful on the bug on pixman_region32_init_rect nor could I come up with a solution for Linux, so I guess there's no other choice besides leaving it out (thank you @iloveeclipse for reverting it).

Unpopular opinion: life is much better with blocking operations and without concurrency/asynchronicity... ;)

I agree (sigh)
