Please review the bug fix for JDK-8208061. The 
runtime/LoadClass/TestResize.java test failed with "Load factor too 
high" when running with CDS enabled at runtime. Dictionary resizing was 
disable when UseSharedSpaces was true, which caused the failure.

The fix is to allow resizing for all system dictionaries except for the 
shared dictionary at runtime. The shared dictionary data are from mapped 
CDS archive and does not change at runtime, so resizing is not required. 
The change also adds 'resizable' information to the log output in 

webrev: http://cr.openjdk.java.net/~jiangli/8208061/webrev.00
bug: https://bugs.openjdk.java.net/browse/JDK-8208061

Verified with TestResize.java running locally with CDS enabled. Tier1 - 
tier5 tests are in progress.
