[I] [Bug] Getting class not found exception when I try to initialise PulsarClient/PulsarAdmin [pulsar]
selvatlc opened a new issue, #21296:
URL: https://github.com/apache/pulsar/issues/21296
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
### Version
**Environments**
```
karaf - 4.4.3
openjdk version "17.0.6" 2023-01-17
Maven - 3.9.1
```
**Used Dependencies**
```
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar-client-all</artifactId>
<version>3.1.0</version>
</dependency>
```
**Sample Snippet**
```
pulsarAdmin = PulsarAdmin.builder().serviceHttpUrl(adminUrl).build();
pulsarClient = PulsarClient.builder().serviceUrl(clientUrl).build();
```
### Minimal reproduce step
When I try to execute the code by creating a normal JAR and execute it on terminal using java -jar <jar_file>, i'm getting valid response.
If i create an OSGI bundle and installed my code on KARAF, i'm getting class not found exception. Need your help on this
### What did you expect to see?
Pulsar client and admin should be created without making any errors

The bug is not with the Pulsar Clients, but with the way you've created the bundle. Please check the answer I've provided you in the discussion you've opened.
