Misuse Details

Details about the known misuse from the MUBench dataset.

Description:	On line 187 `EXTENDED.charAt()` is invoked without ensuring that the respective string actually has sufficiently many characters.
Fix Description:
Violation Types:	missing/condition/value_or_state
In File:	com/itextpdf/text/pdf/Barcode39.java
In Method:	getCode39Ex(String)
Code with Misuse:	class Barcode39 { /** Converts the extended text into a normal, escaped text, * ready to generate bars. * @param text the extended text * @return the escaped text / public static String getCode39Ex(String text) { StringBuilder out = new StringBuilder(""); for (int k = 0; k < text.length(); ++k) { char c = text.charAt(k); if (c > 127) throw new IllegalArgumentException(MessageLocalization.getComposedMessage("the.character.1.is.illegal.in.code.39.extended", c)); char c1 = EXTENDED.charAt(c 2); char c2 = EXTENDED.charAt(c * 2 + 1); if (c1 != ' ') out.append(c1); out.append(c2); } return out.toString(); } }
