Java 16 and 17 release cadence and migration strategies

Upgrading to Java 17 LTS involves managing new feature cadences and practicing continuous migration routines.

#2 about 8 min

Enabling preview features and incubator modules in Java

Preview features and incubator modules allow developers to test emerging APIs safely before they reach standard integration.

#3 about 3 min

Managing removed APIs and enhanced deprecation practices

The Java JDK utilizes enhanced for-removal annotations to explicitly signal the upcoming deletion of obsolete code abstractions.

#4 about 7 min

Using Java records to create immutable data carriers

Record classes replace boilerplate code for immutable data objects while supporting custom canonical and compact constructor evaluations.

#5 about 7 min

Simplifying object evaluation with pattern matching enhancements

Pattern matching implementations for instanceof operators and switch statements eliminate repetitive variable casting processes.

#6 about 5 min

Enforcing domain constraints with sealed classes and interfaces

Sealed classes explicitly restrict the boundaries of object inheritance to defined sets of internal classes or records.

#7 about 5 min

Leveraging new datetime formatters and stream processing improvements

New core stream extensions execute memory-optimized collections while advanced formatters offer localized representation for relative time periods.

#8 about 11 min

Improving application performance with advanced memory and threading features

Emerging JVM functionality natively handles secure interprocess configurations, orchestrates foreign memory assignments, and preloads environments for virtual threading.

#9 about 5 min

Finding replacements for obsolete and removed Java classes

Maintaining a secure application dependency tree requires removing obsolete abstractions like the Applet API, RMI tools, and outdated protocol algorithms.

#10 about 4 min

Distributing native client installers using the jpackage tool

The jpackage bundle deployment command helps DevOps structures build platform-specific system installers targeted towards optimized container architectures.

#11 about 11 min

Addressing updates on concurrency extensions and code diagnostics

Attendees clarify Java community roles, explore dependency diagnosis flags prior to migration efforts, and conceptualize virtual threading capacities.
