@wtgodbe What needs to be done here? Should the whole signalr.client.java.Tests be quarantined?

I don't think the jdk change I made is related. TIL there are 3 installJdk scripts though.

Looks like it's because tar isn't installed on the cbl-mariner docker image we switched to recently. dotnet/dotnet-buildtools-prereqs-docker#1013 should fix
