Add JavaAPI stubs for missing java.lang.reflect and java.io types; remove author tags #4477

shai-almog · 2026-01-30T18:24:31Z

Motivation

The BytecodeTranslator emitted "no class definition" errors for reflection-related types and java.io.Externalizable during translation, causing downstream iOS build steps to fail.
Providing minimal Java API stubs allows the translator to resolve these referenced types during writeOutput so classes are not purged or translation does not fail.
A missing xcodebuild in CI PATH is an environment/configuration issue that must be investigated separately and is not addressed by these stubs.

Description

Added stub interfaces under vm/JavaAPI/src/java/lang/reflect: GenericArrayType, ParameterizedType, TypeVariable, and WildcardType.
Added IO-related stubs under vm/JavaAPI/src/java/io: Externalizable, ObjectInput, and ObjectOutput.
Removed author tags from the new stub files to match repository style.

Testing

No automated tests were executed for this change.
