      Description

      The dreaded sequel to HARMONY-222. While the one line fix for that prevents the test suite bringing about a rather undignified exit to the VM it doesn't really address the bigger picture of how to cope with user code that marks files as delete-on-exit and also makes use of the System.runFinalizersOnExit() method. Of course the latter method is deprecated but it won't stop some people from adopting it in their code.

      I will attach a test case for dropping into tests/api/java/io/FileTest.java together with some minor tweaks to the build.xml and hyproperties.xml files in modules/luni/make/common that will enable this new test to run. A new support class will also be needed to help run part of the test in a separate VM.

      My suggested fix for this is an update to one class in icu4jni-3.4.jar. I think that we are OK customising that jar for Harmony.

      Best regards,
      George
