In the context of JVM Garbage Collection, what is a 'Stop-The-World' pause?
Multiple choiceMediumchapter-14-curatedpremiumperformance-tuningoutofmemoryerrors
Answer and explanation
Correct answer
C. A pause where all application threads are stopped for GC.
Why
A 'Stop-The-World' pause is when the JVM stops all application threads to perform garbage collection. This is necessary for certain phases of garbage collection but can affect application performance if the pauses are too long.
