A number of GET requests are failing with an HTTP 400 Bad Request response. Looking at the BaseX logs, I find that BaseX is internally throwing java.lang.ArrayIndexOutOfBoundsException for these HTTP 400 Bad Request failures: > > <entry time="05:13:57.193" address="***.***.***.***:*****" user="admin" type="400" ms="3.93">[GET] https://********.*******.ibm.com:10443/BaseX/rest/****/*******.xml; Improper use?
