Hi, thank you. For me it looks like it's fixed in upcoming 1.9.0, however just to be sure cc @Ivan Kylchik

when 1.9.0 is going to be released?

You can expect 1.9.0-Beta in the middle of May or so.

@mglukhikh Actually I am not sure is it fixed or not, because it doesn’t look like interpreter error. By stack trace I can see that this error occur on some fir lazy class when we try to get annotations from it.

Then Zakir, could you please report a :youtrack: issue? It would be also helpful if you try to minimize the issue; probably it's provoked by the access of

createdAt: java.util.Date?

property from the file

TransactionsExtensions.kt

in your code. If minimization will be not possible, then please share the piece of code around this property access.
