This bug is fixed in the 1.53i29 daily build.

I updated the documentation for the str.*() functions, under “String Functions” in the Macro Functions list, so it mentions the version of ImageJ required.
These string functions, where 's' is a string variable, are also available in ImageJ 1.52t and newer: s.charAt(i), s.contains(s2), s.endsWith(s2), s.indexOf(s2), s.lastIndexOf(s2), s.length, s.matches(s2), s.replace(s1,s2), s.startsWith(s2), s.substring(i1,i2), s.substring(i), s.toLowerCase, s.toUpperCase, s.trim.
