All you have to do is to run it with a debugger. It also allows profiling operations to be performed by hotswapping in versions of methods in which profiling code has been inserted.įor the moment, this only allows for newly compiled method body to be redeployed without restarting the application. HotSwap adds functionality to the Java Platform Debugger Architecture, enabling a class to be updated during execution while under the control of a debugger. This feature provides the ability to substitute modified code in a running application through the debugger APIs. HotSwap support: the object-oriented architecture of the Java HotSpot VM enables advanced features such as on-the-fly class redefinition, or "HotSwap". The name of the package depends on the version of the default JDK: repository and now also provides binaries for OS X.ĭCEVM is packaged for Debian and Ubuntu, it's conveniently integrated with OpenJDK and can be invoked with java -dcevm.
