Issue/Introduction
On a new server where Java and Elasticsearch 7.13.1 were installed, while installing Dollar Universe Explorer onto the same server, the DUX install works and completes successfully but the Explorer service then stops running shortly after and will not successfully restart and stay running. In the unistartbui explorer log I am getting the following error message:-
C:\<path_to_java>\bin\java.exe
WARNING: An illegal reflective access operation has occurred

How could we fix the issue?
Can I also know what are the latest versions of Elasticsearch as the documentation references to Elasticsearch 7.13.1 ?
Environment
Release : 7.x
Component: Dollar Universe Explorer
Cause
ElasticSearch database not reachable or correctly configured.
Resolution
Dollar Universe Explorer requires ElasticSearch 7.16, you could use the msi to ease the installation and setup:
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.16.0.msi
Once installed, you can go ahead and install DUX and set the correct port and database name if something was modified while installing it.
