RFR: JDK-8148467: Consistent use of : in the logging

[Bengt Rutisson]

Hi everyone,

Could I have a couple of reviews for this simple change to make the 
logging a bit more consistent?

http://cr.openjdk.java.net/~brutisso/8148467/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8148467

As described by Jenny in JDK-8065344 some of the log messages are 
missing a ":".

Here's are the comments regarding ":" from JDK-8065344:

Parallel Redirty>Parallel Redirty:
  -Other phases has ':' as separator, except for this one.

[34.589s][debug ][gc,ergo,cset] GC(6) Added expensive regions to CSet 
(old CSet region num not reached min).old 2940 regions, expensive: 2940 
regions, min 2940 regions, remaining time: 0.00ms
->[34.589s][debug ][gc,ergo,cset] GC(6) Added expensive regions to CSet 
(old CSet region num not reached min).old: 2940 regions, expensive: 2940 
regions, min: 2940 regions, remaining time: 0.00ms
By adding ":" after old, expensive, min to make the format the same.

Finish choosing CSet. old 0 regions, predicted old region time: 0.00ms, 
time remaining: 0.00
-> Finish choosing CSet. old: 0 regions, predicted old region time: 
0.00ms, time remaining: 0.00
The ':' after old makes the format the same


Thanks,
Bengt
