We should try to make sure that the IAE from ASTNode.setSourceRange is not logged

We experience the same issue but I don't know how to reproduce this. If we have an example, we might be able to ask JDT committers for help.
Probably related to bug 461363 We should print the file name to the log and ideally also the text if it can be obtained somehow without throwing an IAE
GitHub Pull Request 351 created by [kthoms] https://github.com/eclipse/xtext-eclipse/pull/351
PR merged. It will provide a more detailed error message on the type resource for which the IAE is raised. Leaving this error open, we might get more insights after next release on this topic.
