    Description

      JDK-8295159 added some IEEE conformance checks and corrections of the floating point environment on Linux and macOS/BSD , however in case of issues no logging is done .

      Loading shared libraries can corrupt IEEE rounding mode settings, see JDK-8295159.
      This logs
      • whether we had to do the correction
      • whether the correction was successful or not

      An event log dll message entry is generated and the log is printed with -Xlog:os.

      The text logged is
      IEEE subnormal handling had to be corrected after loading <filename>
      IEEE subnormal handling could not be corrected after loading <filename>
