5 months ago Can't proceed without a test case, but I will look into adding some instrumentation that would log which file and which method is being worked on when the error happened. That should help a bit.

5 months ago reoccurrence of #1514, #1420
Similar symptoms and problem spots perhaps, but those are fixed with a reproducer. So this must be an at least slightly different cause.

5 months ago As said I can't reproduce it directly it just "happened" while coding, maybe because there are some compile errors at the moment, for me the code looks like it should not perform an array copy without validate the node is of the correct type and just skip nodes that are not a statement (comments? don't know).

5 months ago I think I got a reproducer now, clone the repository:
https://github.com/eclipse-tycho/tycho
then import tycho/tycho-core project and go to SourceCodeAnalyzerPlugin.java line 117 and place the cursor over getContained() method:
analyzer.getContained().put(packageRef);
^then press F3 and you will get an error popup

Perfect, thanks! I will try to get a fix in for M3, failing that certainly for RC1

5 months ago Smaller test case:
public class X {
public static void main(String[] args) {
for (String sourcePath : args) {
new X() {
public void foo(String file) {
file.hashCode();
}
};
}
}
}Placing the cursor on file in the statement file.hashCode() and pressing F3 triggers java.lang.ArrayStoreException: arraycopy: element type mismatch: can not cast one of the elements of org.eclipse.jdt.internal.compiler.ast.ASTNode[] to the type of the destination array, org.eclipse.jdt.internal.compiler.ast.Statement
Working on it ...

5 months ago @srikanth-sankaran great you found a smaller reproducer :+1: a fix for RC1 would be great as it greatly degrades functionality.

On the case. RC1 is very much the goal.
I'm not sure how to reproduce that but on some of my code getting the following exception when pressing
F3:Exception
