[jdk21u-dev] RFR: 8337102: JITTester: Fix breaks in static initialization blocks

Wed Oct 29 17:47:24 UTC 2025

The backport verified on MacOS/Linux/Windows by manually running JITTester.

Verification involved modifying JITTester code to terminate with non-zero exit code when encountering specific compilation error (a break statement in a static initializer) in the generated code and enabling static initializer generation in configuration file in non-fixed version.

Without the fix in most cases the error is reproduced  during the first generation round.
With the fix, there is no error for 10s of rounds.
