vm_info: OpenJDK 64-Bit Server VM (25.265-b01) for linux-ppc64le JRE (1.8.0_265-b01), built on Jul 28 2020 11:16:00 by "mockbuild" with gcc 4.8.5 20150623 (Red Hat 4.8.5-44)

Resolution

Do a clean install from rhel-7-for-power-9-rpms. rhel-7-for-power-le-rpms packages are not supported on power9.

Root Cause

Power8 packages from rhel-7-for-power-le-rpms installed on power9.

Diagnostic Steps

• Verify the cpu architecture cat sosreport/proc/cpuinfo | grep POWER or in the fatal error log (e.g. cpu : POWER9 (architected), altivec supported).
• Check sosreport/sos_commands/yum/yum_list to see if any packages from rhel-7-for-power-le-rpm are installed.
