PrintVtableStats has not been very useful and reported information may not be accurate neither. Please see the CR and comments in JDK-8275413 for details.

  • PrintVtableStats is none product flag, so does not require a CSR to remove it.
  • The patch also removes Klass::array_klasses_do() and families, as PrintVtableStats is the last use.
  • InstanceKlass/ArrayKlass::array_klasses_do(void f(Klass* k, TRAPS), TRAPS) have no use, remove them as well.

Progress

  • Change must not contain extraneous whitespace
  • Commit message must refer to an issue
