When setting up an APM to do thread dumps when the server agent reports high CPU usage, the thread dump seems to be in a specific/proprietary encoding and cannot be opened by any of the normal means. Including Eclipse Memory Analyser Tool (MAT) and/or text editors. Although, APM can open them just fine.

Is there any way of decoding it so it is plain text?
