Simplify control flow

Streamline code by simplifying control flow structures to improve readability. Eliminate unnecessary nesting and verbosity by applying these guidelines:

1. Remove redundant else blocks after return, break, continue, or throw statements: ```java // Prefer this: if (condition) { return value; } return otherValue;

// Over this: if (condition) { return value; } else { return otherValue; }

2. Use early returns to reduce nesting levels:
```java
// Prefer this:
if (condition1) {
    // Handle special case
    return;
}
// Handle normal case

// Over this:
if (condition1) {
    // Handle special case
} else {
    // Handle normal case
}

1. Use concise conditional expressions for simple assignments: ```java // Prefer this: String scheme = ctx.pipeline().get(SslHandler.class) == null ? “http” : “https”;

// Over this: String scheme = “http”; if(ctx.channel().pipeline().get(SslHandler.class) != null) { scheme = “https”; }

4. Follow consistent loop patterns used throughout the codebase:
```java
// Use this pattern for polling loops:
for (;;) {
    Object msg = queue.poll();
    if (msg == null) {
        break;
    }
    pipeline.fireChannelRead(msg);
}

// Instead of while or other variations
