Broken on JDK7

[vladimirvivien]

When running on JDK7, several commands (including ps and connect) cause the following error:

Oddly enough, I'm seeing the same issue on 1.6.0_39 x86_64:

[root@worker1 jmxcli-0.1.2]# java -jar cli.jar

Thanks for reporting. This is on track to be fixed in the next release.

[unhuman]

Any update on this? Busted for me.

[galmeida]

Any workarounds?

$ java -version
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) Client VM (build 20.6-b01, mixed mode, sharing)

[vladimirvivien]

Guys sorry for delay. Looking at this to have a fix soon.

I'm currently using JMXTerm:

I also saw the same error on 1.6.0_24-b07. It looks like a tools.jar issue. As a workaround I added the full path of tools.jar (only included in a jdk and not in a jre?) to the Class-Path entry of MANIFEST.MF in cli.jar. That works but is no more than a quick unpractical hack.

Somehow you have to add tools.jar to the classpath without editing MANIFEST.MF. But including -cp or setting the classpath environment variable don't seem to work.

Same problem here, going with JMXTerm

[tekumara]

Same problem here on Mac OS X JDK 1.7.0_45 :(

[stentrup]

It works when I copy the tools.jar from the JDK's lib directory into the lib directory of jmx-cli

I think this has to be run inside a JDK environment. I am successfully running this project inside of the docker image java:openjdk-8-jdk.

docker run --rm -it java:openjdk-8-jdk
wget https://github.com/downloads/vladimirvivien/jmx-cli/jmxcli-0.1.2-bin.zip
unzip jmxcli-0.1.2-bin.zip && cd jmxcli-0.1.2
cp $(find / -name tools.jar) lib/
java -jar cli.jar

@xrl Awesome!!!!!

[JensRantil]

@xrl I understand it was a while ago you made your comment, but do you also remember if you verified commands such as ps worked as expected? Just like in the issue description, I can start the application, but ps doesn't work.

[vladimirvivien]

@JensRantil I am not actively maintaining this project. ps should work ok.

[voiprodrigo]

ps and connect do not seem to work, they hang. I'm running openjdk in a CentOS7 system. I copied the tools.jar from the JRE to the lib/ dir, otherwise it would give exception

Java version: 1.8.0_141
OS: Linux, Version: 3.10.0-693.17.1.el7.x86_64
jmx-cli > connect pid:181247

Update: ps doesn't work, but I was able to use connect host:port and list Mbeans. Good enough for me!

[vladimirvivien]

@voiprodrigo awesome to know!!!
