Jetty connector is not supported on JDK version less than 17

[sdyavanapelli]

I am getting below error after upgrading jersey-client 3.1.7 from 3.1.5 and also jersey-jetty-client 3.1.7.

I have read the documentation and I am using java 21 and maven 3.9.6 version.

jakarta.ws.rs.ProcessingException: Jetty connector is not supported on JDK version less than 17.

        </dependency>

I have tested my changes with jersey-jetty-connector with version 3.1.6 and 4.0.0.M1 , both of them are working fine but the issue is only with the jersey-jetty-connector : 3.1.7

Note : we are loading the org.glassfish.jersey.jetty.connector.JettyConnectorProvider as spi.

This is weird, jersey-jetty-connector 3.1.7 is almost identical to 3.1.6. Check

• 3.1.6
• 3.1.7

[sdyavanapelli]

yes. The error is only coming from 3.1.7 but not in 3.1.6 and 4.0.0-M1 version, but we have to use 3.1.7 version, can you please look into this.

[sdyavanapelli]

It seems that the jersey-jetty-connector-3.1.7 jar is not generating correct profile for jdk 21 , please check.

[jansupol]

That's just confusing. You'd get the same result from 3.1.6. It is a multi-release jar, and the proper classes are in META-INF/versions/17. The class you show is just to warn about using the improper JDK version.

[sdyavanapelli]

I suspect this Line is missing in 3.1.7 version in MANIFEST.MF "META-INF .versions.17.org.glassfish.jersey.jetty.connector;version="3.1.7". can you check the dependency provided in maven repo : https://mvnrepository.com/artifact/org.glassfish.jersey.connectors/jersey-jetty-connector/3.1.7

[sdyavanapelli]

any update @jansupol .

[jansupol]

I can see the Export-Package: contains META-INF.versions.17.org.glassfish.jersey.jetty.connector;version="3.1.7". But that line should not be relevant outside of OSGi.

[jansupol]

@sdyavanapelli You can try 3.1.8 if that helps.

[jansupol]

I am closing this as not an issue in Jersey.
