[jdk13u-dev] RFR: 8255908: ExceptionInInitializerError due to UncheckedIOException while initializing cgroupv1 subsystem

Fri Jan 22 10:52:09 UTC 2021

I'd like to backport 8255908 to 13u for parity with 11u.
The patch doesn't apply cleanly since 13u doesn't have cgroups v2 support (JDK-8231111), so it reapplied manually to similar places in cgroupv1/Metrics.java and cgroupv1/SubSystem.java.
Tested with tier1 and container tests.
