One call to org.netbeans.shortcuts.Installer$ActionInstaller.handleFileType() leads to 160 calls to I/O, that should not be done from EDT. Passing to editor, but I am not sure where the "shortcuts" module is coming from, it has strange package name...
Sorry, I changed the package name to avoid confusion. I search for a solution to fix the slowness.
