Weird java.lang.OutOfMemoryError

by GreyBox » Sat Sep 28, 2024 3:58 pm

First - big thanks for the nice program!
Maybe no help actually needed here [:)]

I have two laptop with Ubuntu 22.04.4 LTS and and 24.04 LTS (both KDE)
SweetHome3D 64bit v7.4 (and v7.5 now), on both laptops SweetHome folders are identical (main folder and .eteks) - copied them with rsync.

The file has size ~12.3M, it was created on U22.04 and later copied to U24.04 where I added more levels and more furniture. Now it has size ~14.1M.
I copied it back to U22.04 and tried to open. SH3D doesn't show any errors, after processing it shows just the same new empty file.

I tried to remove .eteks folder so SH3D didn't have any plugins and additional furniture - it didn't help.

On U24.04 SH3D has standard -Xmx2g in the script and it can open the file without any issues.
Initially I tried to increase memory limit on U22.04, even set 8g - it didn't help. Upgraded to v7.5 - didn't help too.
And lucky I decided to try the last time to adjust memory limit before post here "plzz help111". [>:)] So I set 16g and finally it was able to open the file.

Weird that when I set 16g and opened the file - in About it shows:
Java 1.8.0_202 - 64bit - 0,1 / 14,2 GB
so as far as I understand it says that used just ~100M of memory. [:-/]

In console I can see following errors (8g limit):

Just to let you know.


And another question - a bit annoying thing, in Task Switcher I see not one SH3D window but many windows and just one of them can be displayed / switched. Sometimes it more than 10 windows. So when SH3D opened it's imposible to use ALT+Tab to switch tasks - too many "empty" windows to scroll. I didn't find if it can be fixed somehow
