IJ47895: JVM FAILS TO START WITH ERROR -89 WHEN /PROC IS MOUNTED WITH THE OPTION HIDEPID=2

APAR status

• Closed as program error.

Error description

• Error Message: Error: Port Library failed to initialize: -89
  .
  Stack Trace:
  .
  

Local fix

• Remount the /proc filesystem without the hidepid option.
  

Problem summary

• The cgroup v1 container detection code requires that the pseudo
  file /proc/1/cgroup is accessible. If /proc is mounted with the
  option hidepid=2, a user without root privileges will not be
  able to access /proc/1/cgroup, and a JVM launched by that user
  will fail to start with the following error:
  Error: Port Library failed to initialize: -89
  Error: Could not create the Java Virtual Machine.
  Error: A fatal exception has occurred. Program will exit.

Problem conclusion

• The OpenJ9 JVM has been updated to print a warning in this
  scenario instead of exiting.
