Improve MimeTypeUtils to handle the case of only a delimiter passed [SPR-14124]

[spring-projects-issues]

Tomoya Honjo opened SPR-14124 and commented

MimeTypeUtil#parseMimeType throws java.lang.ArrayIndexOutOfBoundsException when only delimiter ";" passed as the argument. Because in the method it parse the argument by StringUtils.tokenizeToStringArray(mimeType, ";"); but, it returns an empty array only passed the delimiter, so the exception is thrown by this next line String fullType = parts[0].trim();

For such a case, there is the dedicated exception InvalidMimeTypeException which express passed mimetype string cannot be parsed, so it's better to throw the exception.
