An important reason is that the expected output doesn't match due to different languages.

 STDERR:
  stdout: [];
  stderr: [??: ?? emptynumbootstrapmethods1 ???? main ??, ?? main ?????:
    public static void main(String[] args) 
 ?? JavaFX ?????????javafx.application.Application
 ]
  exitValue = 1

E.g., Test runtime/classFileParserBug/TestEmptyBootstrapMethodsAttr.java with the locale:

LANG=en_US.UTF-8 \
LC_ALL=C \
