And I'd like to have similar useful utilities for OpenJ9.  I know I can configure -Xdump or use Diagnostic MBean to get a threaddump or heapdump, but it is not convenient for me.\r\njstack, jmap and other openjdk tools use Attach API to ask VM for a specific operation. So to make these  tools support OpenJ9 I want to extend Attach API implementation.\r\nI want to add two command names in jcl/src/java.base/share/classes/com/ibm/tools/attach/target/Command.java.\r\nAfter that, I will implement these commands in \r\njcl/src/java.base/share/classes/com/ibm/tools/attach/target/Attachment.java. To get java dump / heap dump I will call jcl/src/openj9.jvm/share/classes/com/ibm/jvm/Dump.java"},"comment":{"url":"https://api.github.com/repos/eclipse/openj9/issues/comments/410043082","html_url":"https://github.com/eclipse/openj9/issues/2543#issuecomment-410043082","issue_url":"https://api.github.com/repos/eclipse/openj9/issues/2543","id":410043082,"node_id":"MDEyOklzc3VlQ29tbWVudDQxMDA0MzA4Mg==","user":{"login":"pshipton","id":18122812,"node_id":"MDQ6VXNlcjE4MTIyODEy","avatar_url":"https://avatars1.githubusercontent.com/u/18122812?v=4","gravatar_id":"","url":"https://api.github.com/users/pshipton","html_url":"https://github.com/pshipton","followers_url":"https://api.github.com/users/pshipton/followers","following_url":"https://api.github.com/users/pshipton/following{/other_user}","gists_url":"https://api.github.com/users/pshipton/gists{/gist_id}","starred_url":"https://api.github.com/users/pshipton/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pshipton/subscriptions","organizations_url":"https://api.github.com/users/pshipton/orgs","repos_url":"https://api.github.com/users/pshipton/repos","events_url":"https://api.github.com/users/pshipton/events{/privacy}","received_events_url":"https://api.github.com/users/pshipton/received_events","type":"User","site_admin":false},"created_at":"2018-08-02T19:36:06Z","updated_at":"2018-08-02T19:36:06Z","author_association":"CONTRIBUTOR","body":"Seems fine so far.\r\n@pdbain-ibm fyi, and any concerns?"}}
