Misuse Details

Details about the known misuse from the MUBench dataset.

Description:	On line 265, `StringTokenizer.nextToken()` is invoked without prior check of `hasMoreTokens()`. This usage may be safe from context, since the tokenized value is an RBG color value which has a known number of tokens. However, the usage is unsafe against invalid values and we, therefore, consider it a misuse. (Same finding as `mudetectxp-7`)
Fix Description:
Violation Types:	missing/condition/value_or_state
In File:	com/itextpdf/text/html/WebColors.java
In Method:	getRGBColor(String)
Code with Misuse:	class WebColors { /** * Gives you a BaseColor based on a name. * * @param name * a name such as black, violet, cornflowerblue or #RGB or #RRGGBB * or RGB or RRGGBB or rgb(R,G,B) * @return the corresponding BaseColor object.
