HotswapAgent is a Java agent providing unlimited runtime class and resource redefinition, enabling real-time code changes without application restarts. It works with enhanced JVMs like DCEVM/JBR and integrates with frameworks via plugins.
Use cases
- reload java classes without restarting the application
- speed up java development by avoiding redeploys
- hot reload spring hibernate classes at runtime
- live code changes inside a docker container
- set up hotswap with intellij and dcevm
When to choose
- you want to eliminate the change-restart-check cycle in Java development
- you need framework-aware hot reloading (Spring, Hibernate, etc.)
- you develop inside restricted environments like Docker
When to avoid
- you need production-grade hot patching with commercial support
- your JVM cannot use DCEVM/JBR variants
- you only need simple method-body hotswap already provided by IDEs
