// 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.
