Which issue related to ClassLoader can lead to memory-related problems?

The issue related to ClassLoader that can lead to memory-related problems is primarily class redundancy. When classes are loaded multiple times due to different ClassLoaders or because of redundant class definitions, it can lead to an increase in memory consumption. Each instance of a loaded class occupies memory, and if numerous redundant classes exist alongside each other, the memory footprint can become disproportionate, causing performance degradation and potentially leading to memory leaks.

Additionally, while large classes can contribute to memory issues, the core of the problem often lies in redundancy, as it impacts the heap space efficiency by unnecessarily duplicating the same class definition. Memory-related problems can accumulate through inefficient ClassLoader management, making class redundancy a key factor in understanding ClassLoader-related memory issues.

The focus on class redundancy emphasizes a critical aspect of memory management in Java applications where clarity in class loading can drastically improve performance and memory optimization.
