I worked around the crash by choosing Open JDK 1.7 to run davmail compiled by Open JDK 1.6.
> sudo update-alternatives --config java I believe it is possible that davmail could compile with Open JDK 1.7 and that its build system prevents higher version numbers by mistake. I believe changing the Java runtime might hide the defect. I did not investigate the root cause of the defect. Perhaps, the libraries shown by the traces only receive a corruption from JDK. -- --------------------------------------------------------------------- This transmission (including any attachments) may contain confidential information, privileged material (including material protected by the solicitor-client or other applicable privileges), or constitute non-public information.
