Tag editor displays strange keys and values when (single-)clicking different cells

[floscher]

What steps will reproduce the problem?

1. Open JOSM and download some OSM data
2. Select an already existent element with some tags
3. Select different rows by single-clicking some cells

What is the expected result?

The respective rows highlight, the content of all cells stays the same.

What happens instead?

The contents of the cells change seemingly at random (it's different every time you try it), sometimes only the clicked cell is highlighted instead of the whole row. The cells display strings like {1 = building} or strings that should be displayed in other cells (e.g. wikipedia=access, where the key access displays as the value of the wikipedia tag).

The underlying data doesn't seem to change, only the presentation, because the strange keys/values sometimes change back to the correct keys/values.

See attached video for how that looks.

Please provide any additional information below. Attach a screenshot if possible.

OS: Ubuntu 15.10 64-bit
Java: OpenJDK 8 64-bit
JOSM: r9329 without plugins and empty ~/.josm-folder
