What effect does a high churn rate in Java applications commonly have?

A high churn rate in Java applications refers to the rapid creation and destruction of objects in memory. This can lead to increased temporary object allocation because the Java Garbage Collector frequently works to clean up the objects that are no longer needed. When objects are created and destroyed rapidly, it puts pressure on the memory management system, leading to more frequent allocations and deallocations. This can affect application performance, but primarily, it results in higher demand for memory resources as the system needs to handle more temporary objects at any given time.

Thus, the correct answer highlights the impact of high churn rates on object allocation patterns within Java applications, illustrating a critical aspect of Java's memory management behavior.
