    RE2/J

    RE2/J

    linear time regular expression matching in Java

    ...This makes RE2/J ideal for applications that must handle user-supplied regular expressions securely without the risk of denial-of-service through regex backtracking. While it omits some advanced features like backreferences and certain Java regex options, it supports the vast majority of practical expressions used in production code. RE2/J thus provides a reliable, safe, and scalable alternative for developers.

    RoaringBitmap

    RoaringBitmap

    A better compressed bitset in Java

    Bitsets, also called bitmaps, are commonly used as fast data structures. Unfortunately, they can use too much memory. To compensate, we often use compressed bitmaps. Roaring bitmaps are compressed bitmaps which tend to outperform conventional compressed bitmaps such as WAH, EWAH or Concise. In some instances, roaring bitmaps can be hundreds of times faster and they often offer significantly better compression. They can even be faster than uncompressed bitmaps.

    Spring Security With JWT

    This project is a comprehensive example repository that demonstrates how to secure a Spring Boot application using Spring Security and JSON Web Tokens (JWT). It is built on Spring Boot 3.x and Java 21, and includes integrations such as Spring Security 6.x, JPA (via Hibernate) for persistence, and Redis for session/token management. The goal is to show how to migrate from stateful, session-based auth toward stateless, modern REST API authentication using JWTs, roles, and permission checks. The code covers typical flows like user registration, login, logout, refreshing or invalidating tokens, and endpoint authorization with annotations like @PreAuthorize. ...

    Caffeine

    Caffeine

    A high performance caching library for Java

    ...In some cases a LoadingCache or AsyncLoadingCache can be useful even if it doesn't evict entries, due to its automatic cache loading. To improve integration, JSR-107 JCache and Guava adapters are provided in extension modules. JSR-107 standardizes a Java 6 based API to minimize vendor specific code at the cost of features and performance. Guava's Cache is the predecessor library and the adapters provide a simple migration strategy. Automatic loading of entries into the cache, optionally asynchronously and size-based eviction when a maximum is exceeded based on frequency and recency.
