Solution 1

I just had this exact same problem; the program had been working fine for months and suddenly this error. Some quick debugging with strace shows that it's trying to open:

/tmp/jna/jna6858279656331549999.tmp

Naturally /tmp/jna was owned by another user, and in my case was a week old. I can't even start to explain how the program had been working properly all day and then suddenly fail because it cannot write to this directory.

Anyhow, I sudo chmod'd /tmp/jna to 777 and now everything's fine. Go figure.

Solution 2

So this application is trying to write to the temp directory. Where is this ? It's OS-specific. I don't know which OS you're running, but you can find the location by using the examples here.

Note that you may be able to use that system property (java.io.tmpdir) to provide a new temp directory location, if you can't change the permissions of where this application is writing to.
