Java Null Reference Handling Principles

Java’s ubiquitous NullPointerException stems from Tony Hoare’s 1965 introduction of the null reference—a design he later called his ‘billion-dollar mistake’—and the JVM mitigates its cost by forgoing proactive checks, instead relying on OS signals like SIGSEGV to detect nulls and throw the exception only when they actually occur.

Deadlock Caused by Do-While Loop in Plugin

A mobile app deadlock was traced to a do‑while loop introduced by a weaver plugin that concurrently copied method nodes, causing ASM label‑node mismatches; adding thread synchronization to the method‑cloning process resolved the issue and underscores the concurrency risks of bytecode instrumentation.
