#12730 closed defect (irreproducible)

buildings_tools v31895 rapidly degrades whilst JOSM is open

Description

What steps will reproduce the problem?

  1. Open JOSM_9979 (Java 1.8.0_77)
  2. Draw 4 buildings using the buildings_tool_31895
  3. Attempt to draw a 5th building

What is the expected result?

(mouse-click 1): beginning of a way
(mouse-click 2): establishment of a way at the angle desired
(mouse-click 3): completed building at angle & size desired

What happens instead?

(mouse-click 1): (i) beginning of a way, or:

(ii) beginning of a rectangle

(mouse-click 2): (if (i) for mc1): the tool only allows discrete angles

(as illustration, "0°, 90°, 180°", though actual angle-steps are much smaller than that)

(if (ii) for mc2): the tool completes 'normally', though the figure on the screen is a rectangle & NOT a line.

(mouse-click 2): (if (i) for mc1): (this step is never completed, as it is impossible to accurately draw a building over the top of the Bing image)

Please provide any additional information below. Attach a screenshot if possible.

Behaviour of this kind is normally the precursor to an eventual JOSM crash.
I have learnt to restart JOSM immediately when it begins to display this behaviour.
This is the first time that it has started to display such behaviour so quickly. I normally have to draw many more buildings than 4 before the problem begins.

You were running JOSM with very low memory for this bug report. I guess you have increased it by now, is the problem still reproducible?

System memory was >1GB at the time. Are you suggesting that the issue was a JOSM memory leak?

I haven't done any mappping nor used JOSM for a very long time. I therefore have zero knowledge on the current state of the game.

Resolution: irreproducible
Status: needinfoclosed

JOSM bug report indicates that only 247 MB was allocated to JOSM. I don't know why, but clearly JOSM cannot work properly with so little memory.

For example, this is what my JOSM instance shows:
Memory Usage: 648 MB / 3634 MB (219 MB allocated, but free)

Please reopen if the problem persists and the status report indicates the JVM allows enough memory (1 GB or more).
