Dianshu Liao updated LANG-1771:
-------------------------------
Description:
In org.apache.commons.lang3.ClassUtils, the method "public static String
getShortCanonicalName(final String canonicalName)" returns an incorrect result
when given certain malformed array class name strings. Specifically, for the
input {{{}"[String"{}}}, it incorrectly returns {{"short[]"}} instead of the
expected {{{}"String[]"{}}}.

This issue seems only occurs with input "[String".
Other inputs like: "[I" → returns "int[]" (correct)
"Ljava.lang.String;" → returns "java.lang.String" (correct)
*Version Affected:* {{3.18.0-SNAPSHOT}}
> Incorrect output from ClassUtils.getCanonicalName when input is "[String" in
> version 3.18.0-SNAPSHOT
