Dear Ivan, dear all,
It is hard to give more significant details; the exception stack is attached as a file to my original post. I run the tool using the "java:exec" maven plugin (hence the org.codehaus.mojo.exec.ExecJavaMojo class in the stack). I am aware that running this on a cluster is potentially hazardous. However, I only use the cluster to avoid having to run this tool locally on my own machine. I only launch one job at a time, and therefore I never have two jobs working on the same repository or make use of any parallelization. In fact, the problem already poses when testing on the login node which has the same NFS setup as the worker nodes. I hope this helps, otherwise I am happy to respond to specific questions.
