Task

Add JSpecify annotations to the following 10 classes in the graphql.execution package, following the established JSpecify annotation pattern documented in .claude/commands/jspecify-annotate.md.

Classes to annotate

1. graphql.execution.ExecutionStrategyParameters
2. graphql.execution.FetchedValue
3. graphql.execution.FieldValueInfo
4. graphql.execution.InputMapDefinesTooManyFieldsException
5. graphql.execution.MergedSelectionSet
6. graphql.execution.MissingRootTypeException
7. graphql.execution.NonNullableValueCoercedAsNullException
8. graphql.execution.NormalizedVariables
9. graphql.execution.OneOfNullValueException
10. graphql.execution.OneOfTooManyKeysException

Instructions

Follow the JSpecify annotation process documented in .claude/commands/jspecify-annotate.md:

1. Set each class to be @NullMarked at the class level
2. Remove all redundant @NonNull annotations that IntelliJ may have added
3. Check Javadoc for @param tags mentioning "null", "nullable", "may be null"
4. Check Javadoc @return tags mentioning "null", "optional", "if available"
5. Inspect method implementations that return null or check for null
6. Consider GraphQL specification details when determining nullability
7. For Builder static classes, label them @NullUnmarked and no further annotations needed

Validation

After making changes, run the NullAway compile check:

./gradlew compileJava

If you find NullAway errors, make the smallest possible change to fix them. You can use assertNotNull with a message if needed.

Cleanup

1. Remove each completed class from the exemption list in src/test/groovy/graphql/archunit/JSpecifyAnnotationsCheck.groovy
2. Delete all unused imports from the classes you've annotated
3. Do not make spacing or formatting changes - only make minimal changes necessary for the annotations

Reference

Look at existing annotated classes in the repository for reference patterns.
