Java & JVM

Practical Java, concurrency, memory, class loading and modernization guidance for production services.

Modernizing Java Services Without Freezing Delivery

How to sequence Java, Spring Boot, Gradle, dependency, artifact and cloud migrations while teams continue shipping.

A practical mental model for volatile, synchronized, final fields and happens-before relationships in concurrent Java code.

What class metadata is, how class loaders define reachability and why application reloads can leak metaspace.

How pool size, queue policy and downstream capacity determine whether concurrency improves throughput or amplifies failure.

Why binary floating point is unsafe for money and how to model rounding, scale and comparison explicitly.
