The 23rd edition (FTfJP 2021) will be held virtually in conjunction with virtual ECOOP 2021.<br class=""><br class="">We welcome short or long, completed or in-process contributions, particularly those that will generate discussion and promote numerous new research directions.<br class=""><br class=""><a href="https://conf.researchr.org/track/ecoop-issta-2021/ecoop-issta-2021-workshop-on-formal-techniques-for-java-like-programs" class="">https://conf.researchr.org/track/ecoop-issta-2021/ecoop-issta-2021-workshop-on-formal-techniques-for-java-like-programs</a><br class=""><br class=""><br class=""><b class=""><font size="4" class="">23rd Workshop on Formal Techniques for Java-like Programs</font></b><br class="">Formal techniques can help analyse programs, precisely describe program behaviour, and verify program properties. Modern programming languages are interesting targets for formal techniques due to their ubiquity and wide user base, stable and well-defined interfaces and platforms, and powerful (but also complex) libraries. New languages and applications in this space are continually arising, resulting in new programming languages (PL) research challenges.<br class=""><br class="">Work on formal techniques and tools and on the formal underpinnings of programming languages themselves naturally complement each other. FTfJP is an established workshop which has run annually since 1999 alongside ECOOP, with the goal of bringing together people working in both fields.<br class=""><br class="">The workshop has a broad PL theme; the most important criterion is that submissions will generate interesting discussions within this community. The term “Java-like” is somewhat historic and should be interpreted broadly: FTfJP solicits and welcomes submission relating to programming languages in general, beyond Java, including C#, Scala, etc.<br class=""><br class="">Example topics of interest include:<br class=""><br class=""><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Language design and semantics<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Type systems<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Concurrency and new application domains<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Specification and verification of program properties<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Program analysis (static or dynamic) Program synthesis Security<br class="">Pearls (programs or proofs)<br class=""><br class=""></div>FTfJP welcomes submissions on technical contributions, case studies, experience reports, challenge proposals, and position papers.

We welcome both complete and incomplete technical results; ongoing work is particularly welcome, provided it is substantial enough to stimulate interesting discussions.<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Short Papers (2 pages, excluding references) should advocate a promising research direction, or otherwise present a position likely to stimulate discussion at the workshop. We encourage e.g. established researchers to set out a personal vision, and beginning researchers to present a planned path to a PhD.<br class=""></div>All submissions and reviews will be managed within EasyChair. Submissions should be made via <a href="https://easychair.org/conferences/?conf=ftfjp2021" class="">https://easychair.org/conferences/?conf=ftfjp2021</a>. There is no need to indicate the paper category (long/short).<br class=""><br class="">Both types of contributions will benefit from feedback received at the workshop. Submissions will be peer reviewed, and will be evaluated based on their clarity and their potential to generate interesting discussions. Reviewing will be single blind, there is no need to anonymize submissions.<br class=""><br class="">The format of the workshop encourages interaction. FTfJP is a forum in which a wide range of people share their expertise, from experienced researchers to beginning PhD students.<br class=""><br class=""><font size="4" class=""><b class="">Important dates</b></font><br class=""><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Submission deadline: 26 April 2021 (AoE)<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Notification: 17 May 2021<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Workshop (virtual): date TBD, co-timed with ECOOP 2021 (12-16 July 2021)<br class=""></div><div class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• FTfJP 2021 will happen as a virtual workshop, as will ECOOP/ISSTA 2021.<br class=""></div><font size="4" class=""><b class=""><div class=""><font size="4" class=""><b class=""><br class=""></b></font></div>Formatting and Publication</b></font><br class="">Submissions should be in acmart/sigplan style, 10pt font.
