+tutorial for glsp does not work for java 21, throws:
+
+  $ Unknown OSGi execution environment: 'JavaSE-21'
+  $ org.eclipse.tycho.core.ee.UnknownEnvironmentException: Unknown OSGi execution environment: 'JavaSE-21'
+
+switch to JavaSE 17
+
+  $ update-java-alternatives --list
+  $ sudo update-java-alternatives --set /usr/lib/jvm/java-1.17.0-openjdk-amd64
+
+tutorial for glsp not up to date - git repository modified heavily to accomodate the documentation - the files 
+refered to in the tutorial ar not in the refered repository
+  - proceed to work through the documentation
+
+some unclear aspects regarding the issues:
+
+- general location of affected files
+- adding new content?
+- backup plan
+- devel or new branch?
+
+#1 no bug fix; add mask?
+ - new pnml is empty file - misses model; add defaut model via handler
+
+#2 tasklist file names?
+ - petri_net editor
+
+#3 one page includes all others elements?
+ - one page includes all
+
+#4 node page - maybe example
+ - beispiel - last link
+      https://git-st.inf.tu-dresden.de/dineros/framework/journal-paper-evaluation/-/blob/main/full/model-v5/sorting-wf-synced-safe-sensor-grpn-sig.pnml?ref_type=heads
+ - add extra option for node page with additional metadata
+
+#5 "all elements like channels" - only channels
+ - input only for transitions, markings only for places 
+
+#6 some details pls
+ - elements are in the model but not in the exported pnml
