Java error on launch: Unsupported major.minor version 51.0

See original GitHub issue

Been using Dbeaver extensively for several months and loving it, then had to wipe my machine clean and start over for reasons unrelated. After reinstalling Dbeaver, I now face the following error:

See the log file /Applications/Dbeaver.app/Contents/Eclipse/configuration/XXXXXXXXXX.log

Opening said log file tells me:

I have installed legacy Java from here: https://support.apple.com/kb/DL1572, as suggested during Dbeaver install. Also installed the latest version of Java from here just in case: https://java.com/en/download/ Working on a 2017 MacBook Pro w/ High Sierra 10.13.4.

Any thoughts? Thanks!
