How odd. When I run the tip of test-graal here with 15-ea, I simply get
"No suitable engine found for specified engine name or mime type".

If I go to the parent-project POM and edit the nashorngone profile
so that the two graal jars are added as dependencies of pljava-pgxs,
then I run it again, it finds graal. The dependency-collector debug
output now shows the dependencies:

and the logging you added:

[ERROR] Graal.js
[INFO] setProjectProperty("PGSQL_BINDIR",
...
[DEBUG] com.oracle.truffle.js.scriptengine.GraalJSScriptEngine@66dfc523


So I think the dependency info explains why your run was not finding
graal. I remain baffled regarding how your run was managing to find
Nashorn instead. I wonder if you downloaded a more recent 15-ea than
I have, and there was a chorus of complaints and they put Nashorn back
in for now?

I would be interested to see what a similar Travis run will do after
making sure the graal dependencies are listed: will it then find nashorn,
or graal?
