SSH with Jenkins CLI

When I ssh (I am using Windows 10 with OpenSSH) into jenkins-cli.jar I get the following error:

After trying:

What is the cause of this error, so that I can fix it and SSH into my jenkins instance?

how to prevent thinkorswim's illegal reflective access to java.lang.Classloader.user_paths (2022 - Azul Zulu JDK 11)

I see many illegal reflective access related questions. As of recent ThinkOrSwim has finally implemented that JAVA 11 (the Azul Zulu openJDK 11) be used to launch thinkorswim. It has been warning this day would come. I have "updated" my java version to the extent of my knowledge, but am still receiving the following errors...

I have updated my $PATH variable to show the zulu11 bin...
jesse#jesse-G74Sx:/$ echo $PATH
/usr/lib/jvm/zulu11/bin:/home/jesse/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
I have updated alternatives to force the 'java' command to use the correct repo..
jesse#jesse-G74Sx:/$ sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/zulu11/bin/java 2115801 auto mode
* 1 /usr/lib/jvm/zulu11/bin/java 2115801 manual mode
2 /usr/lib/jvm/zulu8/jre/bin/java 1806401 manual mode
Press <enter> to keep the current choice[*], or type selection number: 1
I then updated my etc/environment file to force $JAVA_HOME to be the corresponding repo by adding the following JAVA_HOME line below the PATH variable line...
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
JAVA_HOME="/usr/lib/jvm/zulu11/"
i dont seem to actually be changing the JAVA_HOME variable,
jesse#jesse-G74Sx:/$ echo $JAVA_HOME
jesse#jesse-G74Sx:/$
however, my main concern is that i need to show other repo's when i run update-alternatives... currently "/usr/lib/jvm/zulu11/bin/java" really ought to be showing another folder from my 'usr/lib/jvm' files ie.
jesse#jesse-G74Sx:/$ cd usr/lib/jvm
jesse#jesse-G74Sx:/usr/lib/jvm$ ls
zulu11 zulu-11-amd64 zulu11-ca-amd64 zulu8 zulu-8-amd64 zulu8-ca-amd64
jesse#jesse-G74Sx:/usr/lib/jvm$
i think if i can get alternatives to show "zulu-11-amd64" or "zulu11-ca-amd64" and could set one of those to the 'java' command, THEN i would have the newer version...
Either my paths are crossed up, or i need to try a different "alternative" but i havent a clue how to get more alternatives listed, nor how to sufficiently set JAVA_HOME..
ps. the only official documentation on how to do this is posted on td's website here

To start with, you should run java -version from where you are running your application. That will clarify which JDK you are actually using.
As the comment says, you are only seeing warnings about illegal reflective access. This is a result of changes between JDK 8 and JDK 9, encapsulating the JDK's internal APIs (which obviously also affect JDK 11). See JEP 260 (https://openjdk.org/jeps/260)
Have a look at this answer on StackOverflow, which goes into more detail and provides some suggestions if you really want to get rid of the messages.
What is an illegal reflective access?

Getting Selendroid standalone to run, Command 'aapt' was not found inside the Android SDK

I have been trying to work on things using selendroid, but I can't get the standalone to run. I have been trying to run the command "java -jar selendroid-standalone-0.15.0-with-dependencies.jar -app selendroid-test-app-0.14.0.apk". But I just keep getting "SEVERE: Error building server: Command 'aapt' was not found inside the Android SDK....". I already referenced This, but it didn't help.

I realized that the picture was a bit small...

SEVERE: Error building server: Command 'aapt' was not found inside the Android SDK. Please update to the latest development tools and try again.
If I left out any information just let me know.
Thanks
EDIT: Here's the latest

Your ANDROID_HOME environment variable is:
C:\Program Files(x86)\Android\android-skd
Please try to change to:
C:\Program Files(x86)\Android\android-sdk
EDIT: Also check that aapt.exe is inside of platform-tools folder, otherwise copy aapt.exe from the last build tools you have, for example:
<android-sdk>\build-tools\22.0.1\aapt.exe
to:
<android-sdk>\platform-tools\aapt.exe

As Mattai said, Selendroid checks for aapt inside platform-tools.
But I was getting the same error even after copying the appt to platform-tools folder.
But worked when I tried after restarting the system!
Thanks Mattai!

Jenkins on Solaris 10 64 bit

I am trying to upgrade my Jenkins on a Solaris SPARC machine. I have been using Jenkins version 1.528 and the java version is "1.6.0_65".
I tried to install 1.565.1 on this server, I was able to start it using "java -jar jenkins.war --httpPort=8086"

I tried other version 1.532 and it worked but it did not work for 1.534
I tried the same version 1.565.3 on a Linux server and it worked there, It had java version "1.7.0_45". Has anyone else faced this issue?

We have got the same problem on Solaris 11.1.
SunOS XXXXX 5.11 11.1 sun4v sparc sun4v
We are so far using 5.32.1 stable working. 5.80.3 not working.
There is no respond on wget. We are using default port 8080 and neither on wget nor on browser a connection can be established.

This issue is not fixed, I have opened a JIRA ticket on Jenkins forum
JENKINS-24357
There are a few related tickets as well

Google App Engine not being accessed via localhost

I am using Mac OS X 10.7.4, app engine sdk 1.7.0, eclipse juno and Java as programming language. The problem is that App runs perfectly well when deployed on appspot but does not work on localhost. When run as web application on port 8888 or any other port (if change it from the configuration), the log represents server is running but when I hit the URL, nothing happens and after some time connection times out. When, debugged it gives the error: Cannot connect to VM. Logs from console for both run and debugged are shown below, kindly help me, I have searched all over the 'net but could not find the solution.
Log when Debugged:

Check the following:
1) If the application has actually started. Enter "ps ax | grep java" in terminal
2) If the application has bound to the port. Install nmap (not sure how to do it on mac) and run it with "nmap localhost". You will see a list of ports and protocols used. If you don't see 8888 with http then something is wrong.

Have you tried running it from the command line? It looks like you're trying to start it in the debugger as well.. no? Try running from the command line, make sure that works. Then try running it from eclipse with "Run" not "Debug" and make sure that works before trying the debugger. Appengine is a little bit particular...
