org.apache.commons.lang3.builder.HashCodeBuilder
te an instance of the lazy initializer ComplexObjectInitializer initializer = new ComplexObjectInitializer(); ... // When the object is actually needed: ComplexObject cobj = initializer.get();

If multiple threads call the {@code get()} method when the object has not yetbeen created, they are blocked until initialization completes. The algorithm guarantees that only a single instance of the wrapped object class is created, which is passed to all callers. Once initialized, calls to the {@code get()} method are pretty fast because no synchronization is needed(only an access to a volatile member field).
