Change unsafe access to jClass in updateGenericTypeInfo

[CaelmBleidd]

Description

In org.utbot.engine.Traverser#updateGenericTypeInfo we access executable for the method under test. It goes into jClass and extracts a method instance from it, which may cause an error if we don't have this class in the classpath. Since this function is not mandatory for analysis, we can just not update generic info and continue analysis instead of falling.

How Has This Been Tested?

Regression and integration tests

There are no additional tests since they highly depend on classpath, project configuration, soot transformation and other options. Unfortunately, the exact combination of these options is lost and the problem occurred on a project with closed code.

Automated Testing

There are no additional automatic tests.

Manual Scenario

There are no manual scenarios.
