When building the coverity-plugin on a machine where someone else has already built it, the tests fail to run with:

java.lang.Error: Failed to create temporary file for jnidispatch library: java.io.IOException: Permission denied

This is because a /tmp/jna directory is created owned by the first user that did the build. Apparently, a new version of JNA fixes this and creates /tmp/jna-${user} instead, so "something" needs to be changed to update that.
