8381222: Running a custom runtime image with AOTCache fails with "Unexpected exception" [jdk26]

[jyukutyo]

This PR allows applications to start with both a custom image and an AOT cache file.

Testing:

1. Reproducer
   The application started successfully with the JDK including this fix.
2. Tier1–5
   No regressions were observed. Some tests failed, but they are not related to this fix.
3. jtreg tests (test/hotspot/jtreg/runtime/cds/appcds/aotCache/)
   All tests passed on all platforms.

• I confirm that I make this contribution in accordance with the OpenJDK Interim AI Policy.
