I checked the dump file and code, and it seems `GarbageFreeSortedArrayThreadContextMap` isn’t used. > In code you can check it with ProviderUtil.getProvider().getThreadContextMapInstance() In version 2.24.3, using ProviderUtil.getProvider().getThreadContextMapInstance(), I got DefaultThreadContextMap because GC_FREE_THREAD_CONTEXT_PROPERTY isn’t enabled https://github.com/apache/logging-log4j2/blob/4aa5efec7f2ee2d4623381cd66c3df3a16a6b9a9/log4j-core/src/main/java/org/apache/logging/log4j/core/impl/Log4jProvider.java#L113-L116 https://github.com/apache/logging-log4j2/blob/4aa5efec7f2ee2d4623381cd66c3df3a16a6b9a9/log4j-core/src/main/java/org/apache/logging/log4j/core/impl/Log4jProvider.java#L127-L129  > in previous versions with ThreadContext.getThreadContextMap() (which returns null for the default map). In version 2.23.1, using ThreadContext.getThreadContextMap() (which returns null for the default map), I got `CopyOnWriteSortedArrayThreadContextMap` based on this logic - `Constants.ENABLE_THREADLOCALS` is true because `isWebApp` is false - `GcFreeThreadContextKey` is false by default value https://github.com/apache/logging-log4j2/blob/fea2a7116160fb1555d578406444b4fc4f0ef2da/log4j-api/src/main/java/org/apache/logging/log4j/spi/ThreadContextMapFactory.java#L139-L146  Additionally, I couldn’t find `GarbageFreeSortedArrayThreadContextMap` in the dump files for either version. -- This is an automated message from the Apache Git Service.
