+jMint operates as Java agent – special kind of application that is launched by (usually HotSpotJVM and is able to modify byte code of classes being loaded by JVM.
 * First, **jMint** loads and parses the modifying behavior in the form of [**_droplet_**](#what-is-droplet) – a Java source file describing the target of modification (class, method, etc) and the modifying code itself.
 * Then, at the time of target class loading, the modifying code gets compiled against the class and **jMint** passes it to JVM alongside with the original byte code just like if it was loaded in usual way.
