Description
Umbrella bug for SA tools which do not provide an option to connect to a  debug server.

Examples:
jhsdb jstack
jhsdb jmap
jhsdb jinfo
jhsdb jsnap

Some of these tools allowed connecting to debug server in JDK 8.
Comments
Backport CSRs have been approved. Approving patch for 11u.

Fix Request for 11u and 13u: In JDK 8 or earlier, some tools (jstack, jmap, jinfo, jsnap) can connect to debug server (jsadebugd). However it has not done so since JDK 9 because jhsdb cannot accept the attach request to debug server. This function should be provided in JDK 11. This change can apply straightly. I've proposed CSR for this in JDK-8230230 (for 11u) and in JDK-8230296 (for 13u).

Discussed with Yasumasa to go through CSR process. If that will be approved we can probably allow this for JDK11 updates. Removing jdk11u-fix-no label now and will wait for CSR.

As Mark said, this issue is not critical, so it to merge to 13 is rejected by project lead. However I think it is regression as I said in fix request. So I want to fix it in the latest LTS release at least.

Hi Yasu, I wouldn't say this is not suitable per se for jdk11u. However, can you please try to get it backported to jdk13u first, too see if it would be accepted there? Furthermore, in case you want to have this in jdk11u (or jdk13u as well) you'll need to file CSR requests for both of these codelines first. Best regards Christoph

Given that the enhancement to 13 was declined, is there any reason that it should be bapckported to 11? It would be very odd for it to be suitable for 11 but not 13. Perhaps I'm missing some important information.

Fix Request for 11u: In JDK 8 or earlier, some tools (jstack, jmap, jinfo, jsnap) can connect to debug server (jsadebugd). However it has not done so since JDK 9 because jhsdb cannot accept the attach request to debug server. This function should be provided in JDK 11. This change can apply straightly after JDK-8223814 (I'm also requesting backport it to JDK 11). In addition, this change is known that it is failed if sadebugd test is run in concurrently. So I'm requesting backport JDK-8227594 to avoid it.

I changed fix version to 14. I continue to work for 14. (I'm waiting for CSR approval for 14 in JDK-8224979)

Enhancement request declined by Project Lead. This enhancement is not critical to the success of the release. Please retarget to JDK 14.

Late Enhancement Request: In JDK 8 or earlier, some tools (jstack, jmap, jinfo, jsnap) can connect to debug server (jsadebugd). However it has not done so since JDK 9 because jhsdb cannot accept the attach request to debug server. This ticket introduces new command line option for jhsdb to connect to debug server. It does not affect to other modes in jhsdb. Thus compatibility risk is none. See CSR (JDK-8224979) for further details.

debug server support is available in tools which extends sun.jvm.hotspot.tools.Tool . AFAICS they are jstack, jmap, jinfo, jsnap.
