The integration tests cannot run on a JDK 26 toolchain today. Every
`verify.groovy` post-build hook dies with:
```
java.lang.IllegalArgumentException: Unsupported class file major version 70
at groovyjarjarasm.asm.ClassReader.<init>(ClassReader.java:200)
at
org.codehaus.groovy.ast.decompiled.AsmDecompiler.parseClass(AsmDecompiler.java:83)
```
The failure mode is worse than a plain failure: the IT's own `build.log`
still says `BUILD SUCCESS`, and only the post-build hook blows up — so a green
run and a red one look the same until you read the stack trace.
The cause is the Groovy that maven-invoker-plugin 3.9.1 brings in, 4.0.27,
whose bundled ASM cannot read JDK 26 (major version 70) class files. 3.10.1
ships Groovy 4.0.31, which can.
Verified on `openjdk 26.0.2`: `mvn -Prun-its verify` goes from failing in
the script interpreter to **Passed: 49, Failed: 0, Errors: 0, Skipped: 0**.
