Some of the existing JCK tests are failing with IndexOutOfBoundsException
during invocation of setText(StringCharacterIterator).

Noticed that when setText() invoked with the StringCharacterIterator with the 
(https://download.java.net/java/early_access/jdk20/docs/api/java.base/java/text/StringCharacterIterator.html#%3Cinit%3E(java.lang.String,int,int,int)

where 'begin' is > 0 the setText() throws IndexOutOfBoundsException.
But, the values are valid.

Please find the attached code snippet.

sample output is - 
"java.lang.IndexOutOfBoundsException: Range [1, 5) out of bounds for length 4
	at java.base/jdk.internal.util.Preconditions.outOfBounds(Preconditions.java:100)
	at "

I see this could be a side effect of JDK-8292387
