Jimfs is an in-memory implementation of Java 7's java.nio.file abstract file system API. imfs supports almost all the APIs under java.nio.file. Jimfs also supports creating file systems that, for example, use Windows-style paths and (to an extent) behavior. In general, however, file system behavior is modeled after UNIX and may not exactly match any particular real file system or platform.

StormCrawler is an open source collection of resources for building low-latency, scalable web crawlers on Apache Storm. StormCrawler is a library and collection of resources that developers can leverage to build their own crawlers. The good news is that doing so can be pretty straightforward. Often, all you'll have to do will be to declare StormCrawler as a Maven dependency, write your own Topology class (tip : you can extend ConfigurableTopology), reuse the components provided by the project and maybe write a couple of custom ones for your own secret sauce.

Mutiny places events at the core of its design. With Mutiny, you observe events, react to them, and create elegant and readable processing pipelines. Mutiny is the perfect companion to tame the asynchronous nature of applications with non-blocking I/O. Declaratively compose operations, transform data, enforce progress, recover from failures and more. 
 
 Mutiny can be used in any asynchronous application such as event-driven microservices, message-based applications, network utilities, data stream processing, and reactive applications.

An opinionated scaffolding library that jump-starts Java projects with an API-first design, secure defaults, and minimal dependencies. Alpine provides the basis for quickly developing a 'Thin Server Architecture'. This type of architecture shifts the role of webapps to being API providers with little or no responsibility for server-side HTML rendering. This type of architecture is perfect for client-side rendered webapps that rely heavily on JSON, for Single Page Applications (SPA), and to power back-ends that drive mobile applications.

OpenTelemetry provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. You can analyze them using Prometheus, Jaeger, and other observability tools. 
 
The OpenTelemetry Collector offers a vendor-agnostic implementation on how to receive, process, and export telemetry data in a seamless way. In addition, it removes the need to run, operate, and maintain multiple agents/collectors in order to support open-source observability data formats (e.g. Jaeger, Prometheus, etc.) sending to multiple open-source or commercial back-ends.

Square stores a reserve of Bitcoins in an offline setting. By having these funds offline, it reduces attack surface and risk of theft. Square's solution is unique, specifically, it leverages FIPS certified Hardware Security Modules (HSMs) to protect the private key material. Funds can be sent from online systems to the cold storage at any time. Moving funds out of cold storage requires a multi-party signing ceremony.

RESTX is the lightweight, modular, feature rich, blazing fast, open source Java REST framework. It shares similarities with modern frameworks like Play! like hot compile and a very productive experience, but focused on REST and pure Java.
 
It is focused more on Rest. This implies that it’s not a general web framework, i.e., there is no templating mechanism. It’s better use with a JavaScript framework on the client side, and you can always use any other templating mechanism to serve your pages.
