The heap space can be increased for JDeveloper by modifying the ide.conf and jdev.conf files of your jdeveloper installation and below is a sample value.

$installationdir\jdeveloper\ide\bin\ide.conf 

AddVMOption  -Xmx1024M
AddVMOption  -Xms128M

$installationdir\jdeveloper\jdev\bin\jdev.conf

AddVMOption  -XX:MaxPermSize=1024M

The maximum size depends on the operating system and if the errors still persist we can disable the SVN connection.

 JDeveloper > Choose Versioning>Configure  and Uncheck 'Versioning support for Subversion'



Tools like Tortoise SVN can be used to do the version control.
