The new test java/awt/Graphics2D/DrawString/IgnoredWhitespaceTest.java came with JDK-8350203 but fails on some Linux machines.
One failure was seen on Linux x86_64 SLES 15.3 :
java.lang.RuntimeException: for text '\\t\\t\\t\\t\\tXXXXX': java.awt.Rectangle[x=300,y=273,width=119,height=26] != java.awt.Rectangle[x=356,y=273,width=119,height=26]

Another on Linux ppc64le RHEL 8.5 :
