Visiting tree hierarchy from value field often triggers premature JVM exit.

[kodecharlie]

1. After starting the template editor, open schema.json.
2. In the left panel under common assay template, select assay cell line.
3. In the right panel under Values, press Lookup button for the first value with URI http://dto.org/DTO/DTO_000 (corresponding to the Name field BRENDA tissues and cell lines).
4. If you the template editor does not immediately crash after pressing on the Lookup button, then press on the Hierarchy tab in the Lookup panel that pops up. Search for some terms, scroll, left-click. At some point, the JVM should crash.

I am suspicious this is a JVM version issue, but am not sure.

Here are diagnostics printed by the JVM to my bash console after the JVM crashes:

I was running into that (or something analogous) after I updated to the latest macOS. Updating to the latest Java 8 runtime fixed it, so try that first...
