I uploaded new webrev:

- if (!ex.getMessage().contains("Invalid com.sun.management.jmxremote.port
number")) {
+ if (!ex.getMessage().contains("For input string: \"apa\"")) {
What is the motivation for this change?
It seems, the original comparison is better.
"ex" is AttachOperationFailedException.
We can get the result as below when we run StartManagementAgent:
-------------
[runApplication] Error: Invalid com.sun.management.jmxremote.port number: apa
[runApplication] jdk.internal.agent.AgentConfigurationError:
java.lang.NumberFormatException: For input string: "apa"
[runApplication] at
jdk.management.agent/sun.management.jmxremote.ConnectorBootstrap.startRemoteConnectorServer(ConnectorBootstrap.java:336)
-------------
I think we should check exception message in AttachOperationFailedException.
In fact, jtreg fails at this point in my environment.
I'd expect a check for some exception name, not for details like: For input string:
"apa".
Should we remove this comparison?
What tests did you run to make sure there are no regressions?
I've tested the following testcases:
- hotspot/jtreg/serviceability/attach
- hotspot/jtreg/serviceability/dcmd/jvmti
- jdk/com/sun/tools/attach
There are more tests related to dynamic attach in closed, nsk.aod.testlist and
30+ attach tests in nsk.jvmti.testlist.
I'm not sure, if they are included into any of the Mach5 testing levels. Will
need to check.
We have to make sure these tests are still passed.
I cannot access JPRT and closed testcases because I'm not an Oracle employee.
Can you run them with this change?
Thanks,
Yasumasa

A space is missed after 'try'.
It is odd that all test java classes define exactly the same methods:
sharedObjectName(), jmx() and cli().
Would it better to defin a common base class with these methods?
Otherwise, it looks good.
Thank you for taking care about it!

Hi all,
If we try to attach invalid JVMTI agent via JVMTI.agent_load dcmd, we
will get "Command executed successfully". However, it implies error in
JVMTIAgentLoadDCmd.
This message is from JCmd.java when jcmd does not receive any output
from target VM.
I think HotSopt/jcmd should return useful error message to users to
understand the cause of failure.
I uploaded webrev for this issue. Could you review it?

This change is work fine on Fedora 26 x86_64 as following jtreg testcases:
- hotspot/jtreg/serviceability/attach
- hotspot/jtreg/serviceability/dcmd/jvmti
- jdk/com/sun/tools/attach
I cannot access JPRT. So I need a sponsor.
(I cannot test it on other platforms.)
Thanks,
Yasumasa
