Hi JB, Just following up on the issue below. I realize this is really a Felix issue, so would it be best for me to submit a Jira to that project? I realize you’re attached to that project as well so I don’t want to submit a Jira if it’s already been done at some level.

For what it’s worth, you can find the JDBC driver here: https://mvnrepository.com/artifact/com.sap.cloud.db.jdbc/ngdbc<https://urldefense.com/v3/__https:/mvnrepository.com/artifact/com.sap.cloud.db.jdbc/ngdbc__;!!PoMpmxQzTok3!u96K7v6YQfqnV0XMYyZg1U_V3cdYSocWCHRKbjj-c1MP5P3pKA26R6_i-zwqciM$> To be clear, the bundle resolves but the AssertionError mentioned occurs when you try to run a query.

I guess you can create a Jira at SAP.

The JDBC driver in question is SAP HANAm file ngdbc-2.7.7.jar (or ngdbc-2.5.52.jar as well). Karaf 4.30, openjdk-14.0.2, Windows Server 2016. Should I create a Felix Jira issue for this?

Can I reproduce it easily (just installingg SAP driver for instance) ? Regards JB Le 29 déc. 2020 à 19:31, Leschke, Scott <slesc...@medline.com<mailto:slesc...@medline.com>> a écrit : I have a JDBC driver jar (SAP HANA), that is build both as a bundle and an MRJar file supporting JDKs 1.8, 9, 11. It works fine when I run Karaf using JDK 1.8, but if I try to use a more recent JDK, the driver throws the following Caused by: java.lang.AssertionError: Unexpected Java class loaded under Java version 11 (maximum supported version is 8) at com.sap.db.jdbc.DriverSapDB._checkJavaVersion(DriverSapDB.java:2055) ~[?:?] at com.sap.db.jdbc.DriverSapDB.checkJavaVersionMaximum8(DriverSapDB.java:2030) ~[?:?] at com.sap.db.jdbc.Driver.(Driver.java:17) ~[?:?] An SAP person says they think the classloader isn’t MRJar aware and is loading the incorrect class. I most recently tried this with OpenJDK 14.x. Since OSGi involves lots of classloader magic, might that be the case or might something else be going on here? Thanks and regards, Scott Leschke
