Cause
These errors are caused by some of our 3rd party components. The warnings mostly come because future Java versions are going to slowly deprecate the way classes can be accessed using reflection.
These warnings should not affect any functionality and neither are there any security concerns regarding this. -
Resolution
WORKAROUND
It is possible to omit these warnings by adding the --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED argument in the CLI command. However the functionality hasn’t been fully tested with these arguments.
The modified command would be:
java --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED -jar ./cli-dir/toadedge.jar -compare -workspace workspace/ -fail_on_diff -in_source workspace/xxx.json -in_target connect/xxx.xml -settings ./compare_settings.json -out workspace/xxx/)
STATUS
Waiting for fix in a future release of Toad Edge
