    While Karaf can handle complex deployment scenarios, setting it up and configuring it properly can be more involved compared to other simpler solutions. This complexity can increase the initial setup time and effort.
  • Limited community support
    Despite being an Apache project, the community around Apache Karaf might not be as large or active as other popular frameworks, potentially making it harder to find ample resources or immediate support.
  • Dependency management challenges
    Managing dependencies in Karaf, especially when dealing with multiple third-party libraries and their versions, can become cumbersome and lead to conflicts if not handled carefully.
