Can version incompatibilities arise among libraries combined at the application's startup point?

Yes, when multiple libraries are combined in a single application launch point, version incompatibilities may occur. This is because different libraries can depend on different versions of the same dependencies (such as third-party libraries or frameworks).

Problems can manifest as:

• Class and method conflicts (for example, if the API has changed between versions).
• Runtime errors due to mismatched interface expectations.
• Class loading issues (ClassLoader conflicts).

To resolve such problems, the following are used:

• Dependency management through build systems (Maven, Gradle) specifying specific versions.
• Use of class isolation (for example, through modules or OSGi).
• Updating libraries to compatible versions.

It is important to carefully monitor versions and test integration.
