[jira] [Commented] (WICKET-5118) split object-sizeof-agent into agent and initializer

["Martin Grigorov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-5118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13865228#comment-13865228 ] 

Martin Grigorov commented on WICKET-5118:
-----------------------------------------

http://openjdk.java.net/projects/code-tools/jol/ provides a tool for reading object size.
Unfortunately it is no in a public maven repo. Maybe some day it will be deployed in Maven Central and we can reuse it.

> wicket-objectsizeof-agent cannot easily be used for applications deployed in a web container:
> When the main classloader loads InstrumentationObjectSizeOfStrategy from wicket-objectsizeof-agent-x.x.jar, it fails because the implemented IObjectSizeOfStrategy is loaded later by the webapp classloader only.
> The module should be split into two:
> - the agent which makes the instrumentation available
> - a library containing an IInitializer which registeres a custom IObjectSizeOfStrategy (utilizing the instrumentation from the agent)
