Sometime during work today I had a failure (while trying to open a new project)
The error I get is this:
com.fasterxml.jackson.databind.JsonMappingException: Java heap space
Just for testing I installed the 3.5 beta version with the Java and I get the same exception there as well.
In my openrefine.l4j.ini I use
# initial memory heap size
# max memory memory heap size
