The bit array data structure is implemented in Java as the BitSet class. Unfortunately, this fails to scale without compression. JavaEWAH is a word-aligned compressed variant of the Java bitset class. It uses a 64-bit run-length encoding (RLE) compression scheme. The goal of word-aligned compression is not to achieve the best compression, but rather to improve query processing time. Hence, we try to save CPU cycles, maybe at the expense of storage. However, the EWAH scheme we implemented is always more efficient storage-wise than an uncompressed bitmap (implemented in Java as the BitSet class). Unlike some alternatives, javaewah does not rely on a patented scheme.

Easy to install library for adding dynamic display, control and configuration of java.util.logging to any swing based application. Useful for debugging apps in production situations; can interactively configure logging while an application is running including adding a handler to save logging output to a file. Changes made to an application's default/startup logging can be saved and automatically applied at startup. LogMan "single" library package for use in swing apps. The jar can be executed, "java -jar xxx", for a demo of the library. See com.raelity.logman.demo.Main for an example of adding the library to a swing app.

JPA Security is an Access Control Solution for the Java Persistence API (JPA). With JPA Security your access control can be performed in the database. You may query the database for all objects of a certain type and will receive only the objects you have read access for. This filtering is performed in the database. Unaccessible queried objects will not be loaded into memory. JPA Security enables you to completely remove security-related code from your code-base. All access control may be configured via Annotations or XML. With JPA Security you do not have to change your access control paradigm (but maybe you want to, when you see the great capability of JPA Security). You even can mix access control paradigms easily. JPA Security is not designed to replace current security solutions, but to extend them. It integrates smoothly into the security mechanisms of the Java EE Platform, but may be used with third-party frameworks like Spring Security or in Java SE, too. With the extensibility of JPA Security it is easy to provide your own access control paradigm, access rules storage or login mechanism.

fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists, and queues with a small memory footprint and fast operations; it provides also big (64-bit) arrays, sets, and lists, sorting algorithms, fast, practical I/O classes for binary and text files, and facilities for memory mapping large files. This jar (fastutil-core.jar) contains data structures based on integers, longs, doubles, and objects, only; fastutil.jar contains all classes. If you have both jars in your dependencies, this jar should be excluded.

Programmatically generate, load, modify, and convert Excel .xlsx spreadsheets in your Java applications. GrapeCity Documents for Excel (GcExcel) is a cross-platform high-speed, small-footprint spreadsheet API library that requires no dependencies on Excel. The powerful calculation engine supports 450+ Excel Functions and custom functions to perform complex calculations. GcExcel is 2x+ faster and uses less memory than Apache POI and allows you to save to XLSX, PDF, HTML, CSV, JSON and Images. Deploy your applications to the cloud, Windows, Mac, or Linux.
