    Tested on Oracle OpenJDK 17.0.2 and Azul 17.0.4.
    The Docker distribution of Jeyzer is now running with the Amazon-correto 17 image.
  • Serial garbage collector support (JEYZ-46)
    Serial garbage collector is now supported in standard (JFR and JZR) as it can be used on single processor machines or small VMs/containers.
    Limitation : JFR does not provide the associated memory pool figures (unlike the Jeyzer Recorder).
  • Locker rule priority increased to improve the automatic filtering (JEYZ-52)
  • The process card sheet now displays the GC old and young names (JEYZ-48)
  • The Session Info sheet displays now the list of matching shared profiles (JEYZ-55)
  • The JVM Flags sheet automatically hides the Default flags (JEYZ-56)
    The auto_filter_default_flags in the JVM Flags sheet configuration (jvm-flags.xml) permits to disable it :
    <origin auto_filter_default_flags="false">
  • The Top stacks sheet displays now the executor (JEYZ-54)
  • GC old and young names are now exposed as process card properties : and (JEYZ-48)
  • Bug fix JEYZ-43 : Capture time (duration) usage on the JRockit parser was used as a time stamp
  • Bug fix JEYZ-45 : Menu sheet displayed an invalid counter for the Task sequence group sheet
  • Bug fix JEYZ-49 : CPU Runnable vs CPU capacity monitoring rule did not manage the JFR CPU count
  • Bug fix JEYZ-50 : Jrockit parsing failed on variant
  • Bug fix JEYZ-51 : Invalid zip file error handling improved
  • Bug fix JEYZ-53 : JFR - thread events can be null
  • Bug fix JEYZ-57 : JFR - parsing failed on unexpected duplicate JFR thread events. Those duplicate events are now ignored.
