[Classpathx-discuss] MimeUtility.java handling of default charset

[Øyvind Harboe]

I'm on a quest to compile a native version(using GCJ) of a program that
can send emails with UTF8 encoded subject/body.

The function below in MimeUtility.java can return a null pointer, which
ultimately causes a nullpointer exception.

public static String javaCharset(String charset)
  {
    if (mimeCharsets==null || charset==null)
      return charset;
    String jc = (String)mimeCharsets.get(charset.toLowerCase());
    return (jc!=null) ? jc : charset;
  }
