FULL PRODUCT VERSION :
Java HotSpot(TM) Client VM (build 1.6.0-rc-b88, mixed mode, sharing)
java TableTest

Java(TM) SE Runtime Environment (build 1.6.0-rc-b90)
Java HotSpot(TM) Client VM (build 1.6.0-rc-b90, mixed mode, sharing)

A DESCRIPTION OF THE REQUEST :
With B89 after starting TableTest then the FIRST CLICK of the "Start" button (which loads 10,000 or so rows with random data then produces the time to load console text) is much slower than B88 was. B89 takes 656 ms to load the table. B88 only took 67ms to load the table.

Tests were after a system restart to eliminate any DLLs that may have loaded.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Running TableTest either after the system has been up for a while or
TableTest is closed and restarted, I get 47ms with b90.

However with XP SP2 restart and holding down the left shift key on
restart (don't start startup items), then running TableTest, the very
first time for any java app is when its the slowest 308ms, 391ms, 656ms
& etc. My guess is some dll is being dynamically loaded.

JUSTIFICATION :
  To speed up Java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Faster Table load
ACTUAL -
First table test load is quite slow - see below. This is after a system restart.

C:\USER\JAVA\TABLET~1>java TableTest
Time taken to create table 10 x 10000 = 656ms
Time taken to create table 10 x 10000 = 15ms
