GeoServer uses several additional libraries and pieces of code. We are including the appropriate notices in this file. We'd like to thank all the creators of the libraries we rely on, GeoServer would certainly not be possible without them. There are also several LGPL libraries that do not require us to cite them, but we'd like to thank GeoTools - https://geotools.org, JTS - https://locationtech.github.io/jts/ WKB4J https://wkb4j.sourceforge.net, OpenPDF - https://github.com/LibrePDF/OpenPDF, and J. David Eisenberg's PNG encoder https://www.catcode.com/pngencoder/

The GeoServer Project also thanks J. M. G. Elliot for his improvements on Jef Poskanzer's GifEncoder. Notice is included below on his Elliot's release to public domain and Poskanzer's original notice (which is new BSD). Source code is included in GeoServer source, with modifications done by David Blasby for The Open Planning Project (now OpenPlans).
Since Gif89Encoder includes significant sections of code from Jef Poskanzer's GifEncoder.java, I'm including its notice in this distribution as requested (appended below).
As for my part of the code, I hereby release it, on a strictly "as is" basis, to the public domain.

GeoServer also includes binaries and from Jetty, the standard version can be found at https://www.eclipse.org/jetty/, released under an OSI-approved artistic license. We include the license completely, as some versions will be distributed without full source.
Jetty License
$Revision: 3.7 $ Preamble:The intent of this document is to state the conditions under which the Jetty Package may be copied, such that the Copyright Holder maintains some semblance of control over the development of the package, while giving the users of the package the right to use, distribute and make reasonable modifications to the Package in accordance with the goals and ideals of the Open Source concept as described at https://www.opensource.org.
It is the intent of this license to allow commercial usage of the Jetty package, so long as the source code is distributed or suitable visible credit given or other arrangements made with the copyright holders.
Definitions:
"Jetty" refers to the collection of Java classes that are distributed as a HTTP server with servlet capabilities and associated utilities.
"Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification.
"Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder.
"Copyright Holder" is whoever is named in the copyright or copyrights for the package. Mort Bay Consulting Pty. Ltd. (Australia) is the "Copyright Holder" for the Jetty package.
"You" is you, if you're thinking about copying or distributing this Package.
"Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.)
"Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it.
The Jetty Package is Copyright (c) Mort Bay Consulting Pty. Ltd. (Australia) and others. Individual files in this package may contain additional copyright notices. The javax.servlet packages are copyright Sun Microsystems Inc.

You may make and distribute verbatim copies of the compiled form of the Standard Version of this Package without restriction, provided that you include this license.
You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version.
You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following:
a) Place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as ftp.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package.
b) Use the modified Package only within your corporation or organization.
c) Rename any non-standard classes so the names do not conflict with standard classes, which must also be provided, and provide a separate manual page for each non-standard class that clearly documents how it differs from the Standard Version.
d) Make other arrangements with the Copyright Holder.
You may distribute modifications or subsets of this Package in source code or compiled form, provided that you do at least ONE of the following:
a) Distribute this license and all original copyright messages, together with instructions (in the about dialog, manual page or equivalent) on where to get the complete Standard Version.
b) Accompany the distribution with the machine-readable source of the Package with your modifications. The modified package must include this license and all of the original copyright notices and associated disclaimers, together with instructions on where to get the complete Standard Version.
c) Make other arrangements with the Copyright Holder.
