Description ytx 2016-12-12 03:49:20 UTC 
Product Version = NetBeans IDE 8.2 (Build 201609300101)
Operating System = Linux version 4.4.0-53-generic running on amd64
Java; VM; Vendor = 1.8.0_111
Runtime = OpenJDK 64-Bit Server VM 25.111-b14

Reproducibility: Happens every time

STEPS:
  * Open a java or xml editor;
  * Press any cursor (left, right, up, down), page up/down, home or end keys the disk will be access.

ACTUAL:
  disk is access constantly (if the key is press and hold then the disk is accessed for every repeat, even if the caret at the beginning of the file (i.e. there is no room (space) for the caret to move to) the disk anyway is accessed.

EXPECTED:
  no excessive disk access.

Holding down any cursor key results in constantly writing 150 K/s to disk.

Very annoying with loud hard drives and probably unnecessarily aging SDD drives.

Should be fixed with high priority.

Downgraded to NB 8.1

It's related to file 

USERDIR/config/Preferences/org/netbeans/modules/uihandler.properties

which is written in high frequency

This is caused by issue #262714. The dev. builds works fine, but release82 branch is missing changeset http://hg.netbeans.org/main-silver/rev/8f112f9b30fb. This change enables editor action logging only if netbeans are started with -J-Dorg.netbeans.editor.ui.actions.logging.detailed=true
Comment 5 Martin Balin 2017-04-06 08:17:28 UTC 
Deserves a special patch for NetBeans 8.2.
Comment 6 Miloslav Metelka 2017-04-06 13:40:51 UTC 
Integrated into release82:
8f112f9b30fb transplanted to 3fa24caee530
Comment 7 Miloslav Metelka 2017-04-07 13:14:01 UTC
