A suspicious octal escape sequence was found inside a String literal.
The Java language specification (section 3.10.6) says an octal
escape sequence inside a literal String shall consist of a backslash
followed by:
OctalDigit | OctalDigit OctalDigit | ZeroToThree OctalDigit OctalDigit
Any octal escape sequence followed by non-octal digits can be confusing,
e.g. "\038" is interpreted as the octal escape sequence "\03" followed by
the literal character "8".
