Mathematica 7 java interface problems
aboSamoor | July 22, 2009 | 11:40 amJava interfaces usually brings problems as cpu high usage and rendering difficulties. You can notice that for matlab, Netbeans and Mathematica. I think they have to consider QT4 for cross platform UI library.
Java used mainly in Mathematica in the documentation center, and this usage allocated about 15% of the CPU to Java all the time, to reduce the usage you have to replace JLink folder with patched one.
wget http://download.wolfram.com/download/GM5YM4/JLink.zip- extract the zip file
- Replace the /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/Jlink with the new folder
If you don’t want Java anymore your can use this trick, notice that you will block the documentation center. However, you can use http://reference.wolfram.com instead.
- Renaming the folder
mv /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink_old - OR Making it not executable
chmod a-x chmod a-x /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink
Sources:
- The patched folder
- Renaming option [1][2]

Java will reload when you access the documentation automatically, but you can kill it again afterwards by re-evaluating the instructions above.

Riccardo Iaconelli | April 11, 2010 | 3:18 pmHi!
I’m desperately looking for this JLink file, but it looks like Wolfram removed it from the web. Do you, by any chance, have it still somewhere?
By the qay, It has also been reported that it’s the same thing that shipped with Mathematica 7.0.1.
If you find it, can you please upload it somewhere or send it to me via mail? I’m having a terrible experience because of this very bug.
Thanks a lot!
