JDK-8287647 - VM debug support: find node by pattern in name or dump
Description
This API was added in JDK-8287647. Its matching criteria is more liberal than the common implementations of "*" matches:

- it is always case insensitive
- it allows the pattern to match a subset of the target string

Therefore, it's not possible to use this API to
- perform case sensitive matching
- perform a full string match

Proposed change:

[1] Add a parameter to select case sensitivity
[2] The pattern should match the full string. I.e., the string "abcd" matches "*bc*" but doesn't match "bc*".

(If substring matching is desired, you can just add "*" to the beginning and end of the pattern).
