OutOfMemoryError in JDeveloper 11.1.1.7 after opening SVN versioned projects

Due to being involved in a SOA Suite 11g project, I'm working on JDeveloper 11g (11.1.1.7). I'm not using the SVN related funcionality of JDeveloper (I try to always use the Eclipse SVN plugin, even if I'm not developing in Eclipse). After opening a SVN versioned project in JDeveloper I checked out with Eclipse, I couldn't work anymore due to OutOfMemoryError errors. Soon after I open JDeveloper, I get the following message:

I tried to increase the heap memory through the ide/bin/ide.conf file (AddVMOption -Xmx1024M) but I noticed that either the IDE was being very memory hungry o was suffering from a  memory leak.

I was not disposed to assign the IDE a big memory quantity so, due to the presence of lots of SVN related classes in the stack trace, I disabled that funcionality: Versioning - Configure - uncheck Versioning Support for Subversion 11.1.1.7....

After disabling it, I could work again.
