External Email: Use caution with links and attachments. Hi there, is this behaviour intentional? Seems to me it should either throw in all these cases, or in none of them, but as always, I might be missing something of importance: === Groovy Shell (4.0.5, JVM: 1.8.0_181) Type ':help' or ':h' for help. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- groovy:000> [][0] ===> null groovy:000> [][666] ===> null groovy:000> [][1e9] ===> null groovy:000> [][-1] ERROR java.lang.ArrayIndexOutOfBoundsException: Negative array index [-1] too large for array size 0 groovy:000> [][-3] ERROR java.lang.ArrayIndexOutOfBoundsException: Negative array index [-3] too large for array size 0 groovy:000> === Thanks and all the best, OC
