# ADR-0002 - Avoid using Java serialization

## Date

2012-12-01

## Context

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

- **Performance:**
Java's built-in serialization mechanism is often slower compared to other serialization solutions.

        conditionalRule.setMimeTypePattern("text/.*");

        // Test matching
        ResponseData responseData1 = new ResponseData();
        responseData1.setUrl("http://www.example.com/page");
        responseData1.setMimeType("text/html");
        assertTrue(conditionalRule.match(responseData1));

        // Test non-matching URL
        ResponseData responseData2 = new ResponseData();

            f.include(PublicApi.INSTANCE.getIncludes());
            // Filter out any non-public APIs
            f.exclude(PublicApi.INSTANCE.getExcludes());
        }));
        extension.getKotlinDslSource().from(sourcesPath.getIncoming().artifactView(v -> v.lenient(true)).getFiles().getAsFileTree().matching(f -> {

 * HTTP/2 support allows all requests to the same host to share a socket.
 * Connection pooling reduces request latency (if HTTP/2 isn’t available).
 * Transparent GZIP shrinks download sizes.
 * Response caching avoids the network completely for repeat requests.

OkHttp perseveres when the network is troublesome: it will silently recover from common connection
