JML Workshop 2016 – Bad Herrenalb

JML  meets  Black Forest Cake

International Working Meeting on the Java Modeling Language
Java Modeling Language (JML):
Specification Language Semantics and Use Cases
Wednesday 2 – Friday 4 November 2016
Bad Herrenalb, Germany
The workshop continues the series of JML workshops which already took place in Dagstuhl, Shonan, and Leiden.

Minutes: jml-workshop-2016-minutes.pdf



Scientific Topic

This workshop will put a particular focus on the semantics of JML in face of its diverse application areas like runtime assertion checking, regression testing, static checking, and interactive verification. A preliminary semantical framework will enable us to look into and discuss issues in the semantics of JML. We aim at refinement of the semantical framework targetted an appendix to the JML reference manual.

Moreover, the agenda will also cover the following points:

  • Keeping up with time: JML and Java language features,
  • Broadening horizons: Specifying security (information flow) or concurrency (locksets, permissions) with JML
  • Outlook on tool support
  • A book on JML: Exploring its potential

Venue

This year's JML meeting will take place in a convention centre ("Haus der Kirche") in Bad Herrenalb, a scenic town with 7500 inhabitants in the northern Black Forest, less than 30 km south of Karlsruhe. The centre provides wireless internet access.

The Convention Centre "Haus der Kirche" belongs to the Protestant Church of Baden and combines the expectations of a modern convention and teaching centre with the Christian tradition of hospitality. The centre has been certified by the German Hotel Association and by EMAS (Eco-Managemant and Audit Scheme).

Costs

The workshop fee will be approx. 180€ covering the costs for accomodation (two nights), meals, and facilities in the convention centre. If you stay fewer or more nights, the costs will change accordingly. The costs are directly paid at the center on check-in.

Arriving by public transport

Karlsruhe is connected to the high-speed train net (ICE) and can be reached from the nearest aiports Frankfurt/Main and Stuttgart. In Karlsruhe catch a commuter train "S1 Ettlingen/Bad Herrenalb" which departs in front of the main station. The terminal stop is Bad Herrenalb (sometimes you have to change in Ettlingen). Tickets can be bought on the train from a ticket machine (4,70€, cash only).

Walk from the train station (Bahnhof Bad Herrenalb) (approx. 5-10 min)

The convention center is situated behind the church St. Bernhard at the mountain towards Dobel. The red sandstone church is already visible from the station Bad Herrenalb.

We recommend to take the Bahnhofstraße at the mini-golf course from the station towards Ettlingerstraße. At Ettlingerstraße cross the street at the pedestrian crossing and turn left to continue on Bleichweg for approx. 50m. Then turn right into Flachstreichweg and continue until the end of the road.

The convention center is situated at your right-hand side on the hill. Please ring the bell at the backdoor. If you prefer the main entrance, please walk around the house to the parking lot. From there you will find a path to the main entrance.
