issue with the tWriteJsonField

[RGriveau]

Hello,

I've an issue with the tWriteJsonField component i've never experienced before :

Exception in thread "main" java.lang.IllegalAccessError: superclass access check failed: class nu.xom.JDK15XML1_0Parser (in unnamed module @0x3494556e) cannot access class com.sun.org.apache.xerces.internal.parsers.SAXParser (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.parsers to unnamed module @0x3494556e

I've tried to simplify my job to minimum to be sure.

I'm actually on Mac APPLE M1 19Go

java - version --> OpenJDK Runtime Environment Zulu18.30+11-CA

I've tried to uninstall & reinstall talend, no changes.

When i watch the project POM, i don't have reference to any json library, could it be it?

Does anyone has an idea for it?

Hi

It seems it is a Java version issue, refer to the Compatible Java Environments section on installation guide, make sure you use a compatible Java version for the studio you are using.

Hi Shong,

I'm sure that i have the good version of java because any other job i tried without the twritejsonfield is working well. I have this message only when i use this component.

Hi RGriveau,

”I'm actually on Mac APPLE M1 19Go

Which version of studio are you using? If 8.0, the compatible Java version is 11 or 8, but you are using Java 18.

Sorry i forgot to precise this point.

I'm on talend 7.3.1

Take a look at the following questions, the users have the same issue and they solved it by installing the right Java version. Double check the Java installation on your machine and make sure the Java is configured correctly to JAVA-HOME and path variable.

Actually the issue was linked, but not for the version of java, i had 3 java installed, dunno why. I kept the good version & now it's all good
