+// This example shows a bug in the old BE
+// original issue - KT-49443, this is the reduced example of it.
+// Here the old BE manages to compile the script, because it assumes incorrect constructor of the DefaultEachEntryConfiguration class
+// on generating code for buildZip.
+// The original example from the issue works supposedly because the constructor is not called on the runtime.
+// In this example, uncommenting call to buildZip leads to the runtime exception, while uncommenting the call to copy or
+// moving DefaultEachEntryConfiguration class definition before ZipHelper breaks codegeneration (somewhat expectedly).
+// The JVM IR BE now generates correct error about invalid script instance capturing.
