[I] [Bug]: Lint: "Widget is disposed" errors after closing Show Lint Results (hop)

Adalennis opened a new issue, #8872:
URL: https://github.com/apache/hop/issues/8872

   ### Apache Hop version?
   
   hop-client-2.20.0-20261009.154204-1
   
   ### Java version?
   
   "21.0.11" 2026-04-21
   
   ### Operating system
   
   macOS
   
   ### What happened?
   
   After the Show Lint Results window has been opened and closed, every later lint update (Lint Project, excluding a file, switching projects, opening or editing a file) logs Error notifying lint results listener: Widget is disposed with a stack trace. Nothing breaks, but the log fills with red errors. The panel unregisters itself in an overridden dispose(), which SWT doesn't call when the window closes.

   Minor, same window: the Severity column is too narrow and cuts "WARNING" to "WARNIN".
   
   ### Issue Priority
   
   Priority: 3
   
   ### Issue Component
   
   Component: Hop Gui
