MicroKernelImpl

public MicroKernelImpl()

Creates a new in-memory kernel instance that doesn't need to be explicitly closed, i.e. standard Java garbage collection will take care of releasing any acquired resources when no longer needed. Useful especially for test cases and other similar scenarios.
