Hi Andrus;
Thanks for coming back to me. It seems that for my situation, I need to let
the build tool know that each of the "injectable" classes should be allowed to
be scanned for constructors in the build product by supplying the Graal
build-tool with;
```
-H:ReflectionConfigurationFiles=/...path.../reflection.json
```
The snipped `reflection.json` file looks like;
```
[
{
"name": "org.apache.cayenne.access.DataDomain",
"queryAllDeclaredConstructors": true
},
{
"name":
"org.apache.cayenne.access.dbsync.DefaultSchemaUpdateStrategyFactory",
"queryAllDeclaredConstructors": true
},
....... continued ....
]
```
There are entries for 117 classes. It seems this file can be supplied with the
library jar in some way in order to instruct the Graal build tool. Maybe once
I have this fully working I can add a PR for it to cover the known classes in
the jar(s).
Regards.
