Tests start failing with CrateDB 4.7.0-SNAPSHOT

[amotl]

Hi there,

according to [1,2], the software tests started failing with the upcoming CrateDB 4.7.0, which is currently in development, on behalf of one of its first nightly releases. Maybe someone of you already has an idea why?

The snippet I have been able to catch is:

io.crate.client.jdbc.integrationtests.ConnectionITest > testExecuteBatchPreparedStatementFailBulkTypes FAILED

    java.lang.AssertionError at ConnectionITest.java:219

# Works
CRATE_VERSION=4.6.3 ./gradlew test

# Fails
CRATE_VERSION=https://cdn.crate.io/downloads/releases/nightly/crate-4.7.0-202109080003-2476b1d.tar.gz ./gradlew test

I haven't been able to verify this on my macOS workstation yet, because the test suite currently exclusively operates on Linux.

With kind regards, Andreas.
