This internal module provides ForJava10AndLater, the implementation of the java8-shim adapter that uses newer JDK collection factories and copy operations. Its setCopyOf method uses an unmodifiable LinkedHashSet to preserve encounter order.

It is compiled with maven.compiler.release set to 10 and may use Java 9 and Java 10 APIs, but no newer APIs.

The core library loads this implementation when the running JDK supports it and otherwise uses the Java 8 fallback. Both shim modules are shaded into the published sanitizer JAR; this module is not independently published and is not a supported consumer API.

The build requires JDK 11 or newer. Run from the repository root to build this module and its dependencies:

./mvnw -pl java10-shim -am package

Changes to the shim should also be checked in the final shaded artifact with the full ./mvnw clean verify build.
