Title:
  Setting Java Flight Recorder option forces English locale

Status in openjdk-lts package in Ubuntu:
  Fix Released

Bug description:
  (I don't have access to file bugs upstream at
  <https://bugs.openjdk.java.net/>)

  Platform information:

  $ uname -m
  x86_64

  $ lsb_release -d
  Description:	Ubuntu 20.04.1 LTS

  $ dpkg -S $(readlink -f $(which java))
  openjdk-11-jre-headless:amd64: /usr/lib/jvm/java-11-openjdk-amd64/bin/java

  $ java -version
  openjdk version "11.0.8" 2020-07-14
  OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu120.04)
  OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)

  Test case to reproduce the problem:

  $ cat > JfrOptLocBugRepro.java <<EOF
  public class JfrOptLocBugRepro {
    public static void main(String[] args) {
      System.out.println(new java.text.DecimalFormat("###,###.00").format(1234567.089));
    }
  }
  EOF

  $ javac JfrOptLocBugRepro.java

  Normal behaviour; nb_NO.utf8 is a locale where the thousands grouping
  and decimal symbol is different from en_US.utf8 and is used as an
  example; I believe this problem does not only apply to this locale in
  particular.

  $ LANG=en_US.utf8 java -cp . JfrOptLocBugRepro
  1,234,567.09

  $ LANG=nb_NO.utf8 java -cp . JfrOptLocBugRepro
  1 234 567,09

  Problem description; If a flight recorder option is added, the numeric
  string is no longer formatted according to the locale.

  $ LANG=nb_NO.utf8 java -cp . -XX:FlightRecorderOptions= JfrOptLocBugRepro
  1 234 567,09

  $ LANG=nb_NO.utf8 java -cp . -XX:FlightRecorderOptions=stackdepth=256 JfrOptLocBugRepro
  1,234,567.09

  A cause may be that the flight recorder uses string formatting to
  build some internal debug strings, and this cause a premature and
  incorrect initialization of the locale.
