PROFILE
Brian Hotopp
Worked on the sbt/zinc repository to enhance build stability and modernize classpath handling. Over two months, delivered a robust inner-class analysis path by introducing a classfile-based fallback when reflection fails, preventing NoClassDefFoundError during post-compile analysis. Improved error handling and diagnostics in Scala and Java, ensuring that missing dependencies no longer cause compilation crashes. Later, implemented support for jrt: URLs in ClasspathFilter and resource loading, enabling reliable platform-module class loading under JDK 9+ and resolving SecurityExceptions. These changes increased build reliability and developer experience, demonstrating depth in API development, backend engineering, and cross-version JVM compatibility work.

May 1, 2026May 2026 focused on JPMS compatibility improvements in sbt/zinc. Delivered a feature to accept jrt: URLs in ClasspathFilter and resource loading to load platform-module classes under JDK 9+ and prevent SecurityExceptions in sbt console. The change is tracked as [2.x] fix: Accept jrt: URLs in ClasspathFilter.onClasspath (commit 78abf74936ef4efed5e25bfc2acab7e3f8f1a269), addressing the user-visible issue sbt/sbt#4328. Business impact: more reliable builds on newer JDKs, reduced user-reported issues, and smoother developer experience.

Mar 1, 2026March 2026 (2026-03) focused on hardening the zinc post-compile analysis path to improve build stability in the presence of optional dependencies. The core improvement is robust inner-class handling that avoids crashes when inner classes reference types not on the classpath by introducing a classfile-based fallback and enhanced logging/diagnostics. All changes were implemented in sbt/zinc and are backed by focused tests to ensure resilience across module boundaries.
