Solved: Ubuntu 8.04 64 bit, Eclipse 3.4, Subclipse 1.4.7 and Subversion 1.5

A previous post, a possible solution to the problem of installing Subversion support in Eclipse 3.4 on Ubuntu 8.04 64 bit.
Although this worked much better Eclipse is still crashing under some operations. I've detected a problem while developing an android application, checked out from a subversion repository, when R.java is recreated causing Eclipse to crash.

This time, and convinced to find a solution or being forced to use Windows Vista as a development platform, I paid more attention to the crash log.

As we can see, the problem is not in subclipse or subversive but in the java virtual machine. It's true, that the problem only showed up when we use subversion, but this is another story.
So, to obtain the solution, download jdk-6u11-linux-x64.bin from Sun and install it.
Next step is to tell Eclipse to use this newly installed java.
