Compile error but no line indicators #7467

Open mclaborn opened 3 months ago

mclaborn commented 3 months ago

Apache NetBeans version

Apache NetBeans 22

What happened

This happens to me occasionally, usually when editing a fairly large java file. The icon in the tab will show a red indicator for a compile error, but there are no red indicators on the right gutter to show which lines have the error(s). If I'm lucky enough to find one the errors on my own, the method call will be in italics, showing an error, but there is no red indicator on the right.

Re-opening NetBeans does not help, nor does re-opening the file in question. The only way I've found to recover is to close NetBeans, delete the cache directory, then re-open NetBeans. There has been some discussion on the users mailing list, under a thread "Compile error but no line indicators". Everyone there is also correcting by clearing the cache.

How to reproduce

Cannot reproduce at will. The files where it happens are rather large (> 5000 lines). Maybe some kind of diagnostic tool could capture helpful info?

Did this work correctly in an earlier version?

No / Don't know

Do you see any error notification at the bottom? Can you check messages.log or in View / IDE log and share any errors there?

This sounds similar to #7437 to an extent - I wonder if similar errors show up here?

I'm having it right now, but unlike the OP, restarting netbeans fixes it, and it's not related to the file size. Here's what I got after adding a syntax error:

Finally got an instance of this. There was one exception at the bottom of the NB window - see attached stack1.txt. I'm not sure if it is related - the time in the Notifications window could have been before the error occurred. ide.log is also attached. From that log: com.mm.server.inventory.app.OrderFunctions2 is the file that I was working in.

I cleared the view of the IDE log and then repeated the edit that triggered the problem. Those log entries are at line 2004 in ide.log.

[note to self that might reproduce: replace mydil.createCustomerObject().getByID(o.getCustomerid()) with l_cust_cache.getByID(...)]

Any progress on this? It is really costing me a lot of time.
