[commit-cp] [bugs #11728] String.split() function return worng results for a String with TAB delimiters "t"

[Timo Lindfors]

Follow-up Comment #1, bugs #11728 (project classpath):

I'm not sure but it seems to me that this is caused by

the construct



while (...) {

  ...

  while(empties-- > 0)

    list.add("");

  ...

}



in java.util.regex.Pattern.split(input, limit). Idea is probably to call
list.add empties times. However, if empties is already zero the construct
will decrease it to -1. This will cause incorrect behavior on next iteration
of the while loop and skip one empty token.



The attached patch works for me and your testcase.
