Title:
  java craches with SIGSEGV all the time (arm64)

Status in openjdk-lts package in Ubuntu:
  Expired

Bug description:
  My device: PINE64 RockPro64
  CPU architecture: arm64
  RAM: 4GB

  java -version:
          openjdk version "11.0.9.1" 2020-11-04
          OpenJDK Runtime Environment (build 11.0.9.1+1-Ubuntu-0ubuntu1.20.04)
          OpenJDK 64-Bit Server VM (build 11.0.9.1+1-Ubuntu-0ubuntu1.20.04, mixed mode)

  I attached error log to this report.

  Each time I want to run minecraft server (java -jar server.jar nogui)
  and also any other java executable it works for a while and then
  crashes with SIGSEGV. For example it may crash like that:
