Hello [~subbu]
Thank you for providing a zip file and instructions.
Based on the files you submitted, you are running an ancient version of OSGi
and Equinox, which is at least 10 years old!
According to [https://www.eclipse.org/forums/index.php/t/1111555/] : "Starting
with OSGi Release 7, the OSGi framework must now support imports of java.*".
Version 7 is from April 2018.
When I tested the steps using a recent version of Eclipse Equinox, I did not
see a log file generated. This is the config.ini I used with [Equinox
4.37|https://download.eclipse.org/equinox/drops/R-4.37-202509050730/index.php]:

{quote}In additional to specifying the version of the execution environment via
an osgi.ee requirement, see osgi.ee Namespace, a Bundle may also import java.*
packages using the Import-Package header. Imports of java.* packages by a
bundle will be used during the resolution process, see Resolving Process, to
ensure the bundle has visibility to the requested packages by wiring the
bundle's import of a java.* package to the export of the java.* package by the
Framework's system bundle. However, a bundle always loads classes in java.*
packages via parent delegation. See Parent Delegation. Therefore, a bundle is
not required to import a java.* package to have visibility to the classes in
the package, if the package is present in the current runtime. It only needs to
import a java.* package to have the resolution process ensure the package is
available from the execution environment. This can avoid a NoClassDefFoundError
during execution of the bundle due to a missing java.* package required by the
bundle.

FYI, we generate our bundle metadata using a Maven plugin, to automate the
process as much as possible.
You'll need to update your Equinox version to something more modern to avoid
this issue.
I think this will need to be Equinox 4.12 from 2019 or later, according to
