有 JRebel 的开源替代方案吗

[monetto]

如题，有类似于 JRebel 的开源替代方案吗？ Debug 只能修改方法体，但是不能修改函数类型，参数等...

别的试过，还没 JRebel 一半好用，付费的就是不一样

> 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.

@tinyuu 感谢，但是不支持 JDk6 啊

@monetto 卧槽，现在还在用 JDK6

[tinyuu]

@monetto 哈哈哈 受苦了啊 不行弄个“那啥的 JRebel”

[hantsy]

完全没兴趣。修改代码后，立即跑测试验证。

不用 Debug，我也不会用。

[monetto]

@hantsy 公司的某大型项目 JDK6 的，要启动 10 分钟。

@monetto JRebel 如果我理解的不错，应该只是开发用的时候用的吧。

@hantsy #8 不是吧，java 不用 Debug 直接 println ？或许这就是大佬吧
