   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.
