Description

The issue has been found during the vote for avatica-1.20.0 RC0.

The standalone-server jar in the staged maven repository contains log4j2 classes but they are not relocated.

In previous, Avatica versions (e.g., avatica-1.19.0), log4j classes were all relocated to avoid classpath problems with other libraries/apps potentially using another log4j2 version.

It seems that relocation was dropped in possibly unintenionally in CALCITE-4152.
