With the changes in this PR I am able to run the full build and tests on my Linux ARM64 VM! But at TravisCI org.apache.druid.segment.virtual.ExpressionVectorSelectorsTest fails with OutOfMemoryError in the heap space. According to Async Profiler the most memory allocations are caused by org.apache.druid.java.util.common.StringUtils#format(). I think this method is overused - most of the time simple String concatenation could be used. String#format() is both slow and memory intensive. I've simplified a bit this test to not use StringUtils#format() but this is not enough - it still fails with OOME. -- This is an automated message from the Apache Git Service.
