[8u] RFC: 8172695: (scanner) java/util/Scanner/ScanTest.java fails

[Alex Kashchenko]

Hi,

I'd like to solicit comments and suggestions about the backport of 
JDK-8172695 to 8u.

Jira issue: https://bugs.openjdk.java.net/browse/JDK-8172695

There were a number of changes to ScanTest and to Scanner itself in 9+, 
so to backport 8172695 cleanly the following issues need to be 
backported as well:

8132206: move ScanTest.java into OpenJDK
8132745: TEST_BUG: minor cleanup of java/util/Scanner/ScanTest.java
8072722: add stream support to Scanner [excluding public API changes]
8139414: java.util.Scanner hasNext() returns true, next() throws 
NoSuchElementException
8159545: closed/java/io/Console/TestConsole.java failed with exit code 1 
[not public, see: https://hg.openjdk.java.net/jdk/jdk/rev/e5d52546ba3a ]
8166261: Scanner.nextInt(int) (and similar methods) throws 
PatternSyntaxException
8186157: (scanner) Modify java/util/Scanner/ScanTest.java to fail if 
English Locale unavailable

What would be the preferred way to bring this to 8u? Is it better to 
backport these changes one by one, or just take 8172695 and modify it 
for 8u? Should bugfixes to Scanner itself (8139414 and 8166261) be 
backported in latter case?
