#proxyhotswap

Java Proxy hotswap agent to be used with a DCEVM enabled JVM.

When an interface a java.lang.reflect.Proxy generated proxy implements is modified (method(s) added, removed or changed), the java agent regenerates its class definition and adds static field reinitialization code.

Also works for Cglib proxies. Cglib proxy replacement does not use package names to detect the Class definition generators to cope with repackaged libraries (like the Spring Framework). The java agent transformer just checks the interface name and method name instead. This may cause problems if you have a interface named GeneratorStrategy that also has a method named generate.

java.lang.reflect.Proxy proxy replacement is a one-step process, Cglib on the other hand a two-step one. So for Cglib proxies you may recieve exceptions when the classes are acccessed before the second step has finished.

Usage

Configure the Java VM with the -javaagent option. For example if you already use DCEVM via -XXaltjvm=dcevm then you just need to append -javaagent:C:\path_to_downloaded_file\java-proxy-agent-v0.0.1-alpha-3.jar so it will become -XXaltjvm=dcevm -javaagent:C:\path_to_downloaded_file\java-proxy-agent-v0.0.1-alpha-3.jar

-XXaltjvm=dcevm option is not required for this agent, but DCEVM must be enabled.
