      Grabbing either a character or a substring from a String doesn't work out of the box:

      echo 'foobar'[0]

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use staticMethod org.codehaus.groovy.runtime.DefaultGroovyMethods getAt java.lang.String int

      echo 'foobar'[3..5]
echo 'foobar'[3..-1]

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use staticMethod org.codehaus.groovy.runtime.ScriptBytecodeAdapter createRange java.lang.Object java.lang.Object boolean

      Certainly the first one doesn't look dangerous, and the second is presumably harmless, but I don't know for sure whether whitelisting it has other implications beyond this simple use case.
