[jdk21u-dev] RFR: 8330016: Stress seed should be initialized for runtime stub compilation

Sat Jan 31 03:51:05 UTC 2026

A clean backport of commit [95d2f8](https://github.com/openjdk/jdk/commit/95d2f8072e91e8df80e49e341f4fdb4464a2616e).

Only touches the stress test-related code.

Motivation: ability to set StressSeed for C2 turns out to be quite instrumental in finding and especially reproducing rare C2 code generation bugs amplified by StressLCM and StressGCM flags, thus backporting it.

Tested by running jtreg tier1-4, gtest, jcstress on linux-aarch64.
