Reports serialization

@ningosi we ran into a similar issue after the automated update to Java 8 “222”.

We fixed it and released version 1.18.0 of the reporting module:

https://issues.openmrs.org/browse/REPORT-853

Can you try upgrading to Reporting 1.18.0 and see if that fixes the issue?

You error message looks slightly different than the one we were seeing so it’s possible this is something related but will require further debugging to fix.

Take care, Mark
