Created attachment 276373 [details] eclipse_debug_bug Every time I debug my program first time after I run Eclipse, when it stops at breakpoint, I can see nothing in "Variables" view. Variables and values appear atfer step over to the next line. This bug only occurs after first switch to debug perspective. Eclipse version: Version: 2018-09 (4.9.0) Build id: 20180917-1800 but I noticed this bug in all previous versions I used
Can you check if in Debug view, the the thread is selected. After selecting the thread I can see the variables view populated.
It is selected, but it looks like the "selection event" didn't fire, because when I click again on the thread, variables appear (see attachement). Thanks, it may help me - I don't have to step over or re-debug. But anyway - it should be better, when variables are seen as they should.

Radek, please provide step by step reproduction instructions and please check if this is may be fixed in the 4.10 latest nightly builds.
@Andrey, In the latest build I see that thread is not selected on it's own when we have a switch to debug perspective.

Interesting, can be related to bug 538548 changes we made, but I wonder that Radek mentioned it was broken in all previous releases too. Simeon, what is the state of the patch for bug 540253?, now we've fixed Platform UI issue with phantom view?
Sounds exactly like what we observed in our product, though in our case we needed to switch to debug perspective and back to see the problem. https://git.eclipse.org/r/#/c/131127/ for bug 540253 is in my opinion ready to merge, possibly with the exception with the plug-in versions. I'll check those tomorrow. At the very least we need to merge: https://git.eclipse.org/r/#/c/131127/3/org.eclipse.debug.ui/ui/org/eclipse/debug/internal/ui/views/launch/LaunchView.java This will revert the regression that is highly likely observed here. I'll check the reproduction steps with the changes from this review and without and I'll let you know (again tomorrow). The rest of the changes in the review focus on trying to do something for bug 538548 after the fix for bug 538548 is reverted. The attempts are done only if specific JDT settings are used; those settings guarantee no perspective switch will occur on breakpoint hit and the debug view will not be activated.

I cannot reproduce this if I debug from Java perspective and switch to Debug perspective (when asked by the dialog). But once I switch back to Java perspective, debug and switch again, I can reproduce the problem. With https://git.eclipse.org/r/#/c/131127/ I no longer see the problem. Andrey, please check the review, in particular the plug-in version bumps. I don't see previous bumps for 4.10 but I do see recent commits in the plug-in which don't bump the version. So I'm confused.
Then again, in https://bugs.eclipse.org/bugs/attachment.cgi?id=276374 there is a breakpoint hit green line visible in the editor. This should not available with bug 540253... I'll check on Windows 10...
Yes, I had this problem in previous versions too. I have selected the option (checkbox in dialog popup) to switch perspective automatically, when stops on breakpoint. Step-by-step to reproduce is simple: - run eclipse - toggle breakpoint - do something to stop the program on this breakpoint (eclipse switches perspective) - variables not seen in variables view https://bugs.eclipse.org/bugs/show_bug.cgi?id=540253 looks similar to my problem. When I re-enter debug mode next time, variables are visible. Noticed on both Win 7 and Win 10.

Can you try in a new workspace with a minimal snippet? Can you try with your current workspace with a minimal snippet? I cannot reproduce this behaviour without switching back and forth between Java and Debug perspectives. I also cannot reproduce the screenshot which shows inactive Variables view but the Java editor shows a breakpoint hit. Do you have non-default preferences and if so which? In particular under Window -> Preferences -> Run/Debug -> Launching / Perspectives.

Created attachment 276999 [details] screen recording I didn't change anything here, so settings should be as default.. I only checked the option "autoswitch perspective to debug when stoped on breakpoint". I attached screenshots of my settings. I recorder my screen, how it looks like. Variables won't show up until I click mouse on thread (left side panel) or until I do "step over" when in debug mode.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
