JVM Architecture · interview question
When analyzing a heap dump after a crash, where would you look for evidence of excessive Metaspace usage?
Multiple choiceHardchapter-14-curatedpremiumjvm-architecturemetaspace
Answer and explanation
Correct answer
B. ClassLoader instances
Why
ClassLoader instances are responsible for loading classes into Metaspace. If you observe a large number of active or retained ClassLoader instances in a heap dump, it could indicate excessive Metaspace usage, potentially leading to an OutOfMemoryError.
