Description

Once KAFKA-2316 is merged, we should take advantage of Java 7 features that improve code quality (readability, safety, etc.).

Examples:

• Diamond operator
• Try with resources
• Multi-catch
• String in switch (maybe)
• Suppressed exceptions (maybe)

This issue is for simple and mechanical improvements. More complex changes should be considered in separate issues (using nio.2, new concurrency classes, etc.).
