trestAPi using an method called org.apache.cxf.ext.logging.LoggingFeature() that has a another api called java.util.Set.of(org.apache.cxf.helpers.HttpHeaderHelper.AUTHORIZATION) which is a java 9+ supported method. when I am selecting the java compiler as JDK 8 the complication is giving me error in studio 8. but when I am using studio 7, its not generating the same code for tRest APi. is there any way to downgrade trestapi component to support java 1.8 in talend studio 8?

Hi @Nirupam Samantha , the compatible Java version for Talend Studio 8 is 11, please refer to this document page, but the JDK compiler compliance level should be always set to1.8. Compile Job with other higher levels has not been fully tested and officially supported, no matter for Data Integration or Big Data Jobs. So, have a try to install java 11 and check if you have the same compilation error.

My TAC is on 1.8 and I can't change the studio version to 11. As you mentioned my studio is set to 11 and my compiler is 1.8 but the back end code for tRESTAPI is using a code in backend which needs JAVA 1.9+ hence the error. How I can use the older version of tRESTAPI?

@Nirupam Samantha the source code of component is located in <studio installation directory>plugins\org.talend.designer.components.localprovider_8.0.1.20211104_0248\components, you can backup the tRest component from studio 8, copy the tRest component from Studio 7 and replace the tRest component in Studio 8, and then restart Studio 8 to local the components.
