#2689 Heap space exception when installing an addon
Hello,
Freeplane fail to install an addon and display this message:
L'installation a échoué (The installation failed). Erreur : org.freeplane.plugin.script.ExecuteScriptException: Java heap space.
Here's the relevant section in log.0
STDOUT: juil. 15, 2019 7:26:14 PM org.freeplane.core.util.LogUtils info
INFOS: installing add-on from file:/C:/Users/xxxx/Documents/freeplane/bookmarks/bookmarks.addon.mm
STDOUT: juil. 15, 2019 7:26:27 PM org.freeplane.core.util.LogUtils warn
AVERTISSEMENT: L'installation a échoué. Erreur : org.freeplane.plugin.script.ExecuteScriptException: Java heap space.
Sometimes Freeplane hang for a long time (many minutes) trying to install the addon, sometimes not. During this time java eat >90% of my CPU and 700MB RAM (against 400MB when Freeplane is opened with a empty map). Fast or slow, the result is always the same with the heap space exception.
This is an addon I'm currently developing. Everything was fine until today, when I tried to add some documentation in the addon. This documentation is a mix of html, css and images (svg and gif) files in the zips/doc folder. The content of this folder is not so big: <13MB for 37 files.
I add the addon packaged for publication to this ticket, and also the addon sources.
Freeplane 1.7.9
Java 1.8
Windows 7
8 GB RAM
hi ilive,
please use freeplane.bat and increase freeplane's heap size as described here:

Cheers and Best Regards,

Thank you Felix.
I can install the addon by increasing the heap size.
But this seems to be kind of a not easy fix to ask to regular users who wish to install my addon.
I'm sorry about that. I wrote a really good documentation for this addon but it doesn't look like a good idea to distribute it with this installation problem.
Here's the Private Bytes reported by Process Explorer for different values of java -Xmx, when Freeplane starts and when I install the addon:
Freeplane manage to install the addon as soon as -Xmx is 800M.
Does this feel right ? I'm wondering. I've just got 13M files for the documentation (mostly animated gifs), this isn't so big. Why does Freeplane need so much memory to deal with them ? Is it a Freeplane thing, or is it a java zip library problem ?
Cheers,
lilive
lilive, there are perhaps numerous copies that have to be kept in memory while unpacking and installing the add-on. I suggest that you exclude the detailled descriptions / animated GIFs from your add-on and direct the users to your Github page or to a YouTube video for that instead.
If I find the time I'll investigate if the installer's memory usage can be reduced.
And please add an installation file that I can use for testing purposes.
