Strange jboss-cli.sh error when quiting the session

[Roul Bergsma]

I see this behavior with Wildfly 16 and wildfly 22: When i enter the jboss-cli console and shutdown the wildfly server, I can't quit the session because it will result in a fully hanging SSh session. 

The error message is quite odd:

CLI Terminal Connection (uninterruptable)" java.io.IOError: java.io.IOException: Error executing 'stty icrnl ixon echo echoctl icanon iexten eof ^D intr ^C min 11111111111111111111111111111111 time 11111111111111111111111111111111': stty: invalid integer argument: '11111111111111111111111111111111': Value too large for defined data type

Java version is:

OpenJDK Runtime Environment (build 14.0.2-internal+0-adhoc.root.jdk14u-55692db5e928)

OpenJDK 64-Bit Server VM (build 14.0.2-internal+0-adhoc.root.jdk14u-55692db5e928, mixed mode, sharing) 

OS:

SmartOS (Solaris based)

Hi Roul,

this is a problem with terminal handling on SmartOS.

In order to help debug could you update the bin/jboss-cli-logging.properties with (All the following lines exist in the file, you will have to un-comment some lines and update some others):

logger.org.jboss.as.cli.level=ALL
logger.org.aesh.level=ALL

logger.handlers=FILE

handler.FILE.level=ALL

Then starts bin/jboss-cli.sh, do the steps that show the problem.

The file jboss-cli.log will contain traces. Feel free to send them directly to me.

Thank-you.

JF

Strange, looks like the values for "min" and "time" aren't processed as expected. Aspecialy the "time" which should be 0 (Zero) is also received as 11111111111111111111111111111111

What is the role of common.sh ? 

echo $* | $GREP "\-\-add\-modules"  Doesn't give a result, but i wonder what it would have to return? 

I noticed that the jboss-cli.sh is running with these "options":

 /usr/bin/bash /opt/local/bin/openjdk11-java --add-exports=java.base/sun.nio.ch=ALL-UNNAMED --add-exports=jdk.unsupported/sun.misc=ALL-UNNAMED --add-exports=jdk.unsupported/sun.reflect=ALL-UNNAMED 

Which are "created" by common.sh

Hi,

I have a potential fix for this problem.

Could you rebuild readline from: https://github.com/aeshell/aesh-readline/pull/57

then copy readline/target/readline-2.1.jar to <wildfly install dir>/modules/system/layers/base/org/aesh/main/readline-2.1.jar

then update <wildfly install dir>/modules/system/layers/base/org/aesh/main/module.xml with <resource-root path="readline-2.1.jar"/>

Let me know if that fixes the problem on SmartOS.

Thank-you.

Roul confirmed that the fix works on SmartOS. We need to upgrade aesh-readline, WFCORE-5287[1] tracks the problem.
