The corresponding error occurs when using the pull command of jgit within the osgi bundle.

========================================================================

As a result of the inspection, it seems that the jgit bundle failed to import the javax.management package.

When I wrote the javax.management package in the jgit's manifest file in import-package, I confirmed that it worked normally.

Please check this bug. thank you

Which java version do you use ?
Do you run jgit in an OSGi runtime or using plain Java ?

If you run jgit on Java 9 or later you may need to add a dependency to your application to the javax.management module.

Using OSGi, We also get this problem with jgit version 6.2.0.202206071550-r:
