Description

Add public method ThreadContext::getThreadContextMap that returns a ReadOnlyThreadContextMap view of the internal data structure.

This method will be used by the log4j-core ContextInjectors so the ThreadContextAccess class in the org.apache.logging.log4j package in log4j-core can be removed.

Furthermore this method can be used as a building block by SPI implementators.
