# ADR-0002 - Avoid using Java serialization

## Date

2012-12-01

## Context

In Gradle, we often need to serialize in-memory objects for caching or transmitting them across process barriers, etc.
Java serialization is one way to implement this, however, despite its simplicity of implementation, it has several drawbacks:

        type = "ReportTab"
        param("startPage", startPage)

 * of project dependencies. This optimizes module loading during runtime, as we will only load external
 * modules that are not loaded transitively by other project modules.
 *
 * We perform this filtering, since if we simply include all external dependencies, regardless of whether
 * they are already loaded transitively, there is a measurable performance impact during module-loading.
