@asotona Can you review this patch that migrates MethodTypeDesc creation to static final field access whenever possible? This allows to reuse cached descriptor strings and avoid revalidation. In addition, I dropped the jdkTreePrimitive benchmark for jdk.classfile.Write, which is identical to jdkTree as far as I see.
