Getting reflective access warning in JDBC Connection Component.

MarkM1 — Tue, 29 Aug 2023 15:59:04 GMT

Talend Open Studio 7.3

JVM OpenJDK 11

WARNING: An illegal reflective access operation has occurred

WARNING: Illegal reflective access by org.talend.components.api.component.runtime.JarRuntimeInfo (file:/E:/Talend_XXXX_Model/TOS_DI-Win32-20200219_1130-V7.3.1/configuration/.m2/repository/org/talend/components/components-api/0.28.2/components-api-0.28.2.jar) to field java.net.URL.factory

WARNING: Please consider reporting this to the maintainers of org.talend.components.api.component.runtime.JarRuntimeInfo

WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations

WARNING: All illegal access operations will be denied in a future release

This seems to happen only in the JDBC Connection component

Other components seem to work without warning.

There are other oddities with the JDBC components, like Guess Schema just replaces the schema without opening the schema dialog, and changes to a Query do not propagate even though the dialog to propagate is answered with a yes.

It did not.

Here is the results of java -version:

openjdk version "11.0.19" 2023-04-18

OpenJDK Runtime Environment Temurin-11.0.19+7 (build 11.0.19+7)

OpenJDK 64-Bit Server VM Temurin-11.0.19+7 (build 11.0.19+7, mixed mode)

I put -version in the advanced options of the job, and it showed the same JVM when I ran it.

Hello,

Are you using 32 bit executable for starting the studio?

So far, Talend is supporting only the 64 bit version. That's why only the 64 bit executable for starting the studio is provided. This is because a lot of the third party libraries in the studio runs on 64-bit Java. Hence, 32-bit becomes tricky if a lot of the dependencies are 64-bit java jars.

Hello,

From above log message, we see

file:/E:/Talend_XXXX_Model/TOS_DI-Win32-20200219_1130-V7.3.1

Is there any TOS_DI-win-x86_64.exe in your installation folder?

Could you please make sure you do install your talend open studio for data integration V 7.3.1 completely and run the correct application?

Best regards

I am only using 64 bit. I am unsure why the 64 bit talend install package names the enclosing folder as Win32, but everything in it is 64 bit.

We are running TOS-DI-win-x86_64.exe
