Unable to run Eclipse R console (StatET) after update to 6b22-1.10.4 version to

[sdruso]

Ubuntu 11.04.
Eclipse 3.5 galileo with StatET 0.9.2
R version 2.12.1 (2010-12-16) packages rJava and rj 0.5 installed

The R console within eclipse works until I made the system update.
The openjdk-6 packages version 6b22-1.10.2 has been replaced by the version 6b22-1.10.4.
In our office all the machines that made this update are not able to run the R console within eclipse,
in those that did not made the update the R console still works fine..
Attached the log.error produced by eclipse.
