On my machine with this configuration there is no error Can you attach the full stacktrace And the minimal reproducer

Yan Pujante · Answer

I just tried with a different configuration java 15 kotlin 1 4 21 compose 0 3 0 build141 and I accidentally introduced a compilation error in my code ` Composable invocations can only happen from the context of a Composable function` after which I get the same `cannot assign instance of java util Collections$EmptyList to field ` error That being said I just realized that this secondary exception happen ONLY in IDEA Ultimate It does NOT happen on the command line

Igor Demin · Answer

Yan Pujante · Answer

So I first saw the issue at runtime with config1 then I saw the issue at compilation time with config2 and error in my code It is not an android project It is a compose app I am using the latest available version of IDE Ultimate 2020 3 2 which has the Kotlin plugin version 203 1 4 30 release IJ7148 5

Yan Pujante · Answer

So this is really weird I tried again on the command line outside the IDE and what I am seeing is a crash of the java vm I tried with bot openjdk and the source of truth oracle jdk java version 15 0 2 2021 01 19 and both generates a hard crash of the java VM with core dump and all that The fact that there is a stack trace is understandable It is a little weird that it triggers a core dump of the VM the latest stack trace I got was

Yan Pujante · Answer

I suppose the stack trace is showing that it is the jni layer that is crashing and not the vm

Igor Demin · Answer

Your version of macOs is not the latest We recently discovered that our latest build don t work on macOS Mojave It crashes exactly with this stacktrace We will fix this Until then you can upgrade your OS or downgrade compose to build149

Yan Pujante · Answer

that is correct I am on Mojave I have been using 141 successfully and didn t know which version would be safe I will try with 149 or just wait for the build that fixes it Thank you
