             Summary: [lang] ArrayIndexOutOfBoundsException StrBuilder replace
                 Key: LANG-1276
                 URL: https://issues.apache.org/jira/browse/LANG-1276
             Project: Commons Lang
          Issue Type: Bug
            Reporter: Andreas Skomedal


There is a bug in replace for StrBuilder, seems the use of nonupdated buffer and character
count is off.

new StrBuilder("Dear X, hello X.").replaceAll(StrMatcher.stringMatcher("X"), "012345678901234567");

yields

{noformat}
