(With one > failure not related to this.) IMO #11745 is a bit too verbose, compared to the code that prints the absent method in NoSuchMethodError: https://github.com/openjdk/jdk/blob/d1d2b55ce0b950e07f6e3761983f73fd58079627/src/hotspot/share/interpreter/linkResolver.cpp#L863-L871 Printing the descriptor directly suffices. Field descriptors are described by [JVMS 4.3.2](https://docs.oracle.com/javase/specs/jvms/se20/html/jvms-4.html#jvms-4.3.2). ------------- PR Comment: https://git.openjdk.org/jdk/pull/14624#issuecomment-1604245500
