Keep jcmd in JRE images to enable on demand flight recorder

Open mattnelson opened this issue 7 years ago • 2 comments

The JRE images are purging[1] everything but the jre/bin directory. In order to enable flight recorder[2] on demand[3], jcmd should also be persisted.

jdk images do not have it removed could that not be used to debug things?

We have switched back to the JDK image for now, but we would like to use the JRE image because of the size.
