7006814: sun.util.logging.PlatformLogger ability to override the
output format
The platform logger is using the SimpleFormatter to be same as the
default logging configuration. It prints 2 lines with the
timestamp. For debugging use, 1-line format will be simpler and
adequate. The number of lines output will be half. This fix allows
to switch to 1-line format by setting
"sun.util.logging.oneLineFormat" system property as an interim
solution before 6381464 is fixed.

It seems a bit strange to have the platform logger support this but
not SimpleFormatter. Do you think there would be any compatibility
concerns if SimpleFormatter were changed to emit one line output?
As Eamonn said, I don't think we can change the default of
SimpleFormatter to one line as it would break existing
apps/scripts/tools that depend on the format.
If not then it might be simpler to change it along with the platform
logger so that this property isn't needed. If there is a concern then
an alternative it to change the platform logger so that it emits the
one-line output by default as it's only used in the platform.
When j.u.logging is enabled (e.g. the j.u.logging API is called), it
will use the SimpleFormatter as the default. If the platform logger
uses one-line format, the output will be inconsistent depending on
whether the j.u.logging API is used by the application. Keeping the
default same as j.u.logging avoids the confusion.
