-------------------------------------------------------------
Thanks [~jtulach] and [~jlahoda]! I'm testing both patches based on release113
branch (as it is the more stable) and it has improved) not found. Next I'm
going to check separately them and get some snapshot if I have still some
slowness.

> Key: NETBEANS-4037
> URL: https://issues.apache.org/jira/browse/NETBEANS-4037
> Project: NetBeans
> Issue Type: Bug
> Components: debugger - Java
> Affects Versions: 8.2, 11.1, 11.2, 11.3
> Reporter: matteodg
> Assignee: Jan Lahoda
> Priority: Major
> Labels: performance
> Fix For: 12.0
>
> Attachments:
> org.netbeans.modules.debugger.jpda.ui.SourcePath.annotate.npss,
> org.netbeans.modules.debugger.jpda.ui.SourcePath.getURL.npss

>
> We have a pretty big NetBeans Platform Application (~180 modules and 5
> suites) and when the debugger reaches the first breakpoint it got stuck: the
> tabs Debugging, Variables, Breakpoints, etc. are all with a "Please wait..."
> node and with the NetBeans sampler I took a few snapshots highlighting it is
> spending a lot of time on calls like:
> * {{org.netbeans.modules.debugger.jpda.ui.SourcePath.getURL()}}
> * {{org.netbeans.modules.debugger.jpda.ui.SourcePath.annotate()}}
> which at the end boil down to a lot of calls like:
> * java.util.concurrent.CopyOnWriteArrayList.remove()
> * java.io.File.isFile()
> Attached the snapshots.
> Then if I press Continue the debugger remain stuck: now Pause and Continue
> buttons in the toolbar are disabled...
> I kept close and restarting NetBeans but no luck... I remember got this
> behavior even with NB 8.2, sometimes though it goes through and I'm able to
> debug, but very rarely!
