Provenance

Statement

Java Service Steward was written from scratch in Rust and Java. Its compatibility with the Java Service Wrapper configuration format, command-line conventions, log format and local control protocol was achieved by (1) reading the publicly available product documentation for property and command semantics, (2) observing the externally visible behavior of a GPL-licensed Community Edition build (command lines, log files, PID files and loopback socket traffic), and (3) confirming a small set of interface facts (packet type codes, system property names and the packet framing) that are functional interface elements rather than creative expression. No source code, documentation text or resource files from Tanuki Software have been copied into this project, and the project deliberately does not reproduce the org.tanukisoftware.wrapper Java API. Contributors must not consult Tanuki Software source code while working on this project.

Rules for contributors

• Never open, download, or consult the Java Service Wrapper’s source code, javadoc, or decompiled binaries, including mirrors and forks of the Community Edition.
• Never copy sentences from the Java Service Wrapper documentation into help text, messages, comments, or documentation. Describe behavior in your own words.
• The only permitted sources for interoperability facts are the public product documentation (property and command semantics), this repository’s tests, and black-box observation of externally visible behavior (command lines, log files, PID files, loopback socket traffic).
• Never add artifacts of the Java Service Wrapper (executables, JARs, DLLs) or real deployment configurations to the repository.
• Use the names “Java Service Wrapper” and “Tanuki Software” only nominatively, in documentation, to describe compatibility. Never cite a Java Service Wrapper version number.
• Everything in the repository is written in English.

Review log

• 2026-08-26: structural-similarity review of src/ and java/ found no comments, identifiers or file references derived from the original product’s source; the log-message catalog was reworded in the project’s own voice (see CHANGELOG 0.3.0).
• 2026-08-26: the Java bridge (java/bridge) was written from the project’s own implementation specification. Its classes, method names, threading model and messages are the project’s design; it shares with the original product only the functional interface facts needed to interoperate (packet type numbers, the NUL-terminated packet framing, and the names of the system properties the executable passes to the JVM). The executable contains no third-party class names; launcher substitution is a generic name rule.
