Package: librxtx-java
Version: 2.2pre2-10
Severity: normal
Tags: upstream patch

As reported in:

  http://mailman.qbang.org/pipermail/rxtx/2009-May/10897125.html

java fails with a buffer overflow when a locked serial device is opened from
the library.

I'm attaching a patch that uses snprintf when reporting fhs_lock errors.
