Hi Goetz,
I am sorry about that and thanks for helping to identify the issue.
As I cannot reproduce this on x86 and AArch64, a quick guess is that I may have
missed the code like:
diff --git a/src/hotspot/share/opto/type.cpp b/src/hotspot/share/opto/type.cpp
index 2f4047dfa8e..f7d2f5b2320 100644
--- a/src/hotspot/share/opto/type.cpp
+++ b/src/hotspot/share/opto/type.cpp

Could you please help to have a try?
Thanks,
