Robert Munteanu commented on SLING-12173:
-----------------------------------------
[~cziegeler] - that was my attempt to try out and see if the older plug-in
version has the same problem. It does have it, so both the jakarta.json and
javax.json implementations are problematic - in Eclipse, for me.
I suspect this is a classloader interaction between
- Maven/Plexus
- the OSGi runtime from Eclipse (Equinox)
- the ServiceLoader framework
- m2e
I _could_ try and chase this down across these projects but it seems like a lot
of work. Instead, I am experimenting with using our commons.johnzon dependency
instead the official JSON artifacts, and for now it seems to work fine.
IIUC this would avoid any such classloading issues, and hopefully will not
bring any problems with Maven executions. I'll try to run some tests over the
coming days, but wanted to check what you think of this approach.
