Help>About Eclipse Project SDK>Plugin Info...
The dialog appears instantly using the standard JRE but ~34 sec using J9 
The same long delay is encountered if you try to sort any of the columns in the table.

NOTES:

	The problem is in the sorting code in sortBy*
	I moved the instantiation of the Collator out of the inner class and it opens in
	about 1 second on J9. 
	I wonder if the JIT is doing this optimization for us in the standard JRE.

		I believe instantiating collators is expensive, and assume that JDK caches them whereas J9 may not.
		The method being used is Collator.getInstance(Locale), where the Locale is always Locale.getDefault().

		J9 has been changed to use the IBM (i.e. JDK) implementation of RuleBasedCollator. Also I've added
		a cache for Collator.getInstance(). Look for these changes in the next J9 1.5 drop (approx 09/28/2001).

	RG (9/20/01 5:03:12 PM)
		I've verified that the problem exists using the (09/14/2001) JCL Drop

Problem has been fixed by J9.
Also changed our code to only ask for the collator once rather
than every sort.
