Motivation

FileSystem.isLegalFileName(CharSequence candidate) method, there is a verification logic : candidate.length() > maxFileNameLength. maxFileNameLength is string length. but when file name bytes exceed 255 will cause system errors. java.io.FileNotFoundException : File name too long.

Solution

maxFileNameLength verify file name bytes length

Alternatives

no
