Hi Igor
I have filed an RFE you asked about
https://bugs.openjdk.java.net/browse/JDK-8145297.

Hi Konstantin,
the fix and tests look good to me, but I think you have to wait for OK from
Coleen.
One minor thing —it looks like there are no tests for other s.r.CP methods,
could you please file an RFE against core-libs/j.l.reflect to cover them?
Thanks,
— Igor

Hello
Please review the new version on the patch.
New webrev:
Webrev hotspot: http://cr.openjdk.java.net/~kshefov/8141615/hotspot/webrev.02
Webrev jdk: http://cr.openjdk.java.net/~kshefov/8141615/jdk/webrev.02
What has been changed:
1. Added tests for the new added methods.
2. Removed CP tag codes 100 - 105 from being passed to java and left only codes
from the open JVM spec
(https://docs.oracle.com/javase/specs/jvms/se8/html/jvms-4.html#jvms-4.4-140).
Thanks

Coleen,
Thanks for review

I have a couple preliminary comments. First, there are no tests added with all
this new functionality. Tests should be added with the functionality
changeset, not promised afterward.
I will add tests.
Secondly, I do not like that JDK code knows the implementation details of the
JVM's constant pool tags. These should be only for internal use.
The package "sun.reflect" is for internal use only, so it shouldn’t be a
problem.
My third comment is that I haven't looked carefully at this constant pool
implementation but it seems very unsafe if the class is redefined and relies on
an implementation detail in the JVM that can change. I will have more
comments once I look more at the jvmti specification.
thanks,
Coleen

Hello
Please, review modified webrev.
I have added methods
getNameAndTypeRefIndexAt(int index) - to get name and type entry index from a
method, field or indy entry index;
getClassRefIndexAt(int index) - to get class entry index from a method or field
entry index;
I removed previously added method
getInvokedynamicRefInfoAt(int index) - as it is no more needed now.

Remi,
Thanks for reviewing. Your suggestion sounds sensibly.
May be it also has sense to make a method "getMethodRefNameAndTypeIndex(int
index)" to acquire name-and-type entry index for methods also.

Hi Konstantin,
Technically, getInvokedynamicRefInfoAt should be
getNameAndTypeOfInvokedynamicRefInfoAt because it only extract the nameAndType
value of the InvokeDynamicRef.
In term of API, I think it's better to decompose the API, i.e. to have a method
int getInvokedynamicRefNameAndTypeIndex(int index)
that returns the nameAndType index and to reuse getNameAndTypeRefInfoAt(index)
to get the corresponding array of Strings.
cheers,
Rémi

Hello
Please review an enhancement to add three new methods to
sun.reflect.ConstantPool class.
The following methods are suggested:
public String[] getNameAndTypeRefInfoAt(int index) - returns string
representation of name and type from a NameAndType constant pool entry
with the specified index
public String[] getInvokedynamicRefInfoAt(int index) - returns string
representation of name and type from an InvokeDynamic constant pool entry
with the specified index
public Tag getTagAt(int index) - returns a Tag enum instance of a constant
pool entry with the specified index
These three methods could be used for testing API working with constant
pool, e.g. JVMCI.
