RE: [aspectj-users] String Trimming anyone???

["Ron DiFrango" <rdifrango@xxxxxxxxxxxxxxxxxxx>]

It seems to manipulate the hashCode:
 
Before[Ron's Aspect Company ]

Before[292824200]

After[Ron's Aspect Company]

After[-2000128872]

{Ron's Aspect Company }

 

Any other thoughts....

	Not sure why this is may happen, but try watching if the same string instance is manipulated (print
	some hashCode()).
