What kind of code modification you did? From stack trace it looks the problem is related to java proxy. What frameworks are you using?

michelou commented 5 years ago

Usage of option -Xshare:dump does not depend on any framework. As a reminder CDS helps reduce the startup time of Java applications as well as reduce their memory footprint.

In my case I wanted to generate file c:\opt\jdk-dcevm-11.0.1\bin\server\classes.jsa on Windows (see this report) before comparing your build of OpenJDK 11 with other builds (see this wip).

PS. I'm experimenting with OpenJDK 11 alongside my contribution to the Dotty project.

skybber commented 5 years ago

Thanks and I'm sorry for misinterpreting your question. It looks the problem is the hotswap-agent.jar in lib/hotswap. The CDS is working without it. But it is strange that it complains on Proxy instance, which as I expect should not be part of CDS at all.

skybber commented 5 years ago

Fixed, thanks for reporting. I've disabled HotswapAgent if -Xshare:dump is presented in params.

skybber commented 5 years ago

Btw, I don't know if HotswapAgent is useful for Scala at all. Probably ClassInitPlugin and AnonymousClassPatch plugin could be useful, otherwise it is better to disable HotswapAgent.
