Michael Paus · Answer

I have observed the same issue and just verified that it only happens when I have previously copied some source code into the clipboard as < mikehearn> suggested It shows immediately though for me after launching the application i e I don t have to click into a text field ```Exception java lang ClassNotFoundException com intellij codeInsight editorActions FoldingData while constructing DataFlavor for application x java jvm local objectref class=com intellij codeInsight editorActions FoldingData Exception java lang ClassNotFoundException com intellij codeInsight editorActions FoldingData while constructing DataFlavor for application x java jvm local objectref class=com intellij codeInsight editorActions FoldingData Exception java lang ClassNotFoundException org jetbrains kotlin idea codeInsight BasicKotlinReferenceTransferableData while constructing DataFlavor for application x java jvm local objectref class=org jetbrains kotlin idea codeInsight BasicKotlinReferenceTransferableData Exception java lang ClassNotFoundException org jetbrains kotlin idea codeInsight BasicKotlinReferenceTransferableData while constructing DataFlavor for application x java jvm local objectref class=org jetbrains kotlin idea codeInsight BasicKotlinReferenceTransferableData```

Frankly it smells like a bug What is `application x java jvm local objectref` that sounds like some kind of generic serialized object stream is this some intellij thing or a general piece of infrastructure

at any rate Compose Desktop shouldn t be trying to load arbitrary classes without even a paste operation

The thing is once it started happening a couple weeks ago it never goes away It now happens on every launch of any Compose desktop app in IDEA or in terminal Even when the Finder clipboard shows up empty
