SuspiciousOctalEscape

SuspiciousOctalEscape

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”.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.controversial.SuspiciousOctalEscapeRule
Example(s):



public void foo() {
  // interpreted as octal 12, followed by character '8'
  System.out.println("suspicious: \128");
}
