## Quick Start

### Prerequisites

- Java 21 or higher
- Maven 3.6 or higher

### Installation

Add the following dependency to your `pom.xml`:

```xml
<dependency>
    <groupId>org.codelibs.fess</groupId>

    val connection =
      Http2Connection
        .Builder(true, TaskRunner.INSTANCE)
        .socket(socket.asBufferedSocket(), "peer")
        .pushObserver(IGNORE)
        .build()
    connection.start(sendConnectionPreface = false)
    socket.shutdownOutput()
    assertFailsWith<IOException> {
      connection.newStream(headerEntries("a", longString), false)
    }
    assertFailsWith<IOException> {

        int dataRemaining = 0;
        int dataOffsetFromHeader = 80;

        // Structure size (17 = 0x11)
        SMBUtil.writeInt2(17, buffer, bodyStart);
        // Data offset (byte - offset from header start)
        buffer[bodyStart + 2] = (byte) dataOffsetFromHeader;
        // Reserved
        buffer[bodyStart + 3] = 0;
        // Data length
        SMBUtil.writeInt4(dataLength, buffer, bodyStart + 4);
