Description

Today I updated my fitnesse project to use the 2.9.0 versions of log4-core and log4j-api. Now I am encountering the exception java.nio.charset.UnsupportedCharsetException: cp65001.

However, my project is running well. Logging seems to work anyway.

According to Issue 1888, there was a similar bug, which was fixed in 2.9.0: https://issues.apache.org/jira/browse/LOG4J2-1888. I commented it, but didn't get an answer until now.

I am using ISO-8859-1 on my Eclipse computer to store the files. But the execution environment is plain UTF-8. Therefore I am using those parameters to run my fitnesse project:

• -Dsun.jnu.encoding=UTF8: handed over as JAVA_TOOL_OPTIONS
• -Dfile.encoding=UTF8: handed over as JAVA_TOOL_OPTIONS
• chcp 65001: to switch the Windows console encoding to UTF8

Here is the exception, which is thrown:

C:\Users\admin\Desktop\RabbitDevInstall\Testtool>java -jar RunRabbitRun-2.0-SNAPSHOT-jar-with-dependencies.jar start ./Resources
Picked up JAVA_TOOL_OPTIONS: -Dsun.jnu.encoding=UTF8 -Dfile.encoding=UTF8 -Ds=0
Unable to get Charset 'sun.stdout.encoding', using default UTF-8

Here is my log4j configuration file:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">

    <Console name="Console" target="SYSTEM_OUT">
      <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </Console>
    
    <RollingFile name="RollingFile" fileName="logs/rrr.log"

</Configuration>

And here is my starting script:

SET RRR_RESOURCES=.

SET JAVA_TOOL_OPTIONS=-Dsun.jnu.encoding=UTF8 -Dfile.encoding=UTF8 -Ds=0

chcp 65001

java -version

java -XshowSettings

java -jar ${project.artifactId}-${project.version}-jar-with-dependencies.jar start ./Resources
