Java unlimited runtime class and resource redefinition.
The main purpose of this project is to avoid infamous change->restart + wait->check development lifecycle. Save&Reload during development should be standard and many other languages (including C#) contain this feature.
Features
In contrast to standard Java, where the hotswap is limited to in-body code changes, the DCEVM + HotswapAgent allow following code changes:
- Add/remove/modify class fields.
- Add/remove/modify methods. Add/remove/modify method annotations
- Add/remove/modify classes including anonymous classes. HotswapAgent handless correct anonymous class redefinitions.
- Add/remove static member of classes. HotswapAgent handles static member initialization.
- Add/remove enum values
- Refresh framework and application server settings
The only unsupported operation is hierarchy change (change the superclass or remove an interface).
DCEVM realizes hotswap on JVM level. HotwapAgent does the same on level of Java frameworks and servlet containers. Both projects used together forms excellent combination for daily development not only in Java but also in another JVM languages.
