first of all thanks for the great product - it's a pleasure to work with!
But with the new version 2.12 I encountered a serious change (and big problem for my WFs) concerning the 'JavaSnippet' node. It seems to me that in 2.12 static variables are not re-initialized anymore when re-executing a node.
Example: I have a WF consisting of 'TableCreator->JavaSnippet' where the data in 'TableCreator' conists of 3 lines (1 column: column1) with values 'A', 'B', 'C'. The JavaSnippet contains the following code:
// Your custom variables; static String txt = "Start:"; // Enter your code here: txt += c_column1; out_text = txt;
where 'out_text' points to FlowVariable 'text' (string)!
The first execution of this WF produces 'text='Start:ABC' in both versions ( 2.11.3, 2.12) but re-executing the 'JavaSnippet' (reset->execute) or the whole WF produces ''text='Start:ABCABC' in 2.12 while 'text='Start:ABC' is returned in 2.11.3. This seems to me that the initialization of static variables is now done once PER LIFETIME and not once PER EXECUTION of a node - as it was done in 2.11.3.
This has serious impacts on my workflow, because I used static variables when there was the need to collect information over rows easily in one step (node execution).
