Looks like a JIT issue, stack trace is similar to https://github.com/eclipse-openj9/openj9/issues/22052.

@VermaSh FYI since you're working on #22052

[vij-singh]

Given #22052 has now been resolved (fixed by #22128 and others), can we check if this one is still an issue? @JasonFengJ9 @VermaSh

[JasonFengJ9]

The assertion failure was not seen in recent builds including disabled test runs. Closing, it can be re-opened if the failure occurs again.
