Is this a regression in 4.19, or was it always like this? How big is your workspace, and how many problems are there? Possibly related: - https://bugs.eclipse.org/bugs/show_bug.cgi?id=346011 Previously for the same codebase I was using 'Eclipse IDE for Java Developers' Version: 2019-12 (4.14.0) Build id: 20191212-1212 includes Eclipse Java Development Tools Version: 3.18.600.v20201202-1800 Build id: I20191210-0610 Saving takes around perhaps 0.4-0.6 seconds there (small pause, not a problem in any way, hard to measure accurately how long it took). ------------- RAP/RCP workspace has 12,000 Java files and 38,600 markers (35,617 warnings). Java IDE workspace has same 12,000 Java files and 10,770 markers (9,594 warnings). I am definitely used to working in Eclipse (normally just the plain 'Eclipse IDE for Java Developers') with projects up to 100k Java files and have never seen this problem before. I am not familiar with the Eclipse RCP/RAP, just installed it to try out Bndtools, but I think this may be a regression of some kind. The problem appears to be related to having the Package Explorer open. If I close it and have no project tree, or just have the Navigator, I don't encounter the delays. Looking at the Decorator configuration I didn't find a decorator I could disable to get rid of the Error Markers. getErrorTicksFromMarkers duplicates bug 450663 but there are tiny differences in the calling stacktraces *** This bug has been marked as a duplicate of bug 450663 *** |
Created attachment 285882 [details] thread dump UI consistently blocks for 6+ seconds when saving modified files. Thread dumps strongly indicate it's the ProblemsLabelDecorator for eg. the Package Explorer or Navigator views.
