Zeilen 606 - 623 eingefuegt, um die parallel berechneten Ergebnisse richtig zu filtern
TODO
- Fuer Variance -1 muss das gleiche gemacht werden

# plugin site erstellen
* die JAvaTXCOmpiler DAtei in ein plugin umwandeln und deployen.
* siehe: http://www.vogella.com/tutorials/EclipseJarToPlugin/article.html#convert-jar-files-to-osgi-bundles-with-the-p2-maven-plugin
* AUsführung:
* mvn deploy #erstellt die JAR-Datei und steckt sie in ein lokales Repo (maven-repository)
* mvn p2:site
* mvn package # hier wird die ZIP-Filf zum Einbinden in Eclipse erstellt
# Einbinden in Eclipse
* In Eclipse kann die Zip-FIle wie ein Plugin installiert werden
* Hier tritt FEhler auf. Reflections-Library kann nicht installiert werden. Möglicherweise wird sie auch nicht gebraucht
* Nach dem installieren de.dhbwstuttagrt.JavaTXcompiler zu den DEpendencies des plugins hinzufügen
* Anschließend unter "Overview" auf "Updata Classpath" klicken
# Windows
* JAVA_HOME setzen:
* export JAVA_HOME=/c/Program\ Files/Java/jdk1.8.0_102/

\section{Generics sind notwendig}
Generics können nicht ignoriert werden.
Folgender Fall ist Typisierbar:
\begin{program}
<T> T m1(T x){
return m2(x);
}
m2(x){
m1(1);
m2("Test");
return m1(x);
}
\end{program}
Beim weglassen des Generics T wäre es aber nicht mehr möglich.
Dann erhält jeder Constraint, welcher in Verbindung mit der Methode m1 steht
den selben TPH.
