Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information and also provided ambiguous information.
As for the description being ambiguous: 1. The first paragraph describes a librxtx problem, but the ErrorMessage and Title fields indicates a duplicate of bug #1550950 2. OpenJDK 8 is cited on the first paragraph but the bug is associated to OpenJDK 9 and further on the Package field contains openjdk-9-jdk Please clarify what the actual issue is and provide additional information. At a minimum, we need: 1. The specific steps or actions you took that caused you to encounter the problem. 2. The behavior you expected. 3. The behavior you actually encountered (in as much detail as possible).
