After converting the enclosed jasm file to binaries, javap produces the following output:

Classfile /Users/lkuskov/Downloads/ValueSubClass.class
  Last modified Jan 20, 2026; size 197 bytes
  SHA-256 checksum ce914ff85a7a8f5a2637520f421b91f2a16a5d2a8e2a8614275ff1389cd6dc1f

  this_class: #4 // ValueSubClass
  super_class: #6 // java/lang/Object
  interfaces: 0, fields: 1, methods: 1, attributes: 1

this output contains:

final value class ValueSubClass

while the class flags are reported as:

flags: (0x0030) ACC_FINAL, ACC_IDENTITY

The textual class declaration printed by javap should be consistent with the class access flags.
