sbt jsoniter-scala-benchmarkJVM/test

@plokhotnyuk thanks for reporting this. I've started #589 and so far the issue is not obvious but appears to affect immutable ArraySeqs but not not mutable ones. I will continue to investigate later today.

@pjfanning Thanks for the fast response!

Could it be due to missing of immutable.ArraySeq in factory lists here?

@plokhotnyuk yes, that looks to be the case - I had just found it when I saw your comment - I should be able to merge the fix soon (barring unforeseen CI failures)

[pjfanning]

@plokhotnyuk the 2.14.0-SNAPSHOT with the fix is on Sonatype - I've also backported the fix to 2.13.3+7-9efbe43c-SNAPSHOT.

Fix is in the v2.13.4 release
