RFR 8223593 : Refactor code for reallocating storage

[Pavel Rappo]

Ivan,

There seem to be more places that use a somewhat similar pattern. I was
wondering if you have seen them and decided not to include them in your patch
for some reason (e.g. they really are quite different)?

Here are some of them:

    java.io.BufferedInputStream
    java.io.InputStream
    java.lang.AbstractStringBuilder
    java.nio.file.Files
    java.util.ArrayDeque
    java.util.Hashtable
    java.util.concurrent.ConcurrentHashMap
    java.util.concurrent.PriorityBlockingQueue
    java.util.regex.Pattern.quote

There is also some number of occurrences in the jdk.* modules.
