> --------------------------------------------------------------------------------------------
>
> Key: CXF-5231
> URL: https://issues.apache.org/jira/browse/CXF-5231
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.7.3, 2.7.6
> Reporter: JBE
> Assignee: Freeman Fang
>
> On server side, I have enabled those two flags in order to be able to retrieve the full exception in client :
> {code}
> Message.FAULT_STACKTRACE_ENABLED -> true
> Message.EXCEPTION_MESSAGE_CAUSE_ENABLED -> true
> {code}
> The problem is that one of the exception message contains a line break "\n" character. Thus when the exception is thrown, here is what I have on client side with version 2.7.6 :
> {code}
> java.util.NoSuchElementException

> After debugging, I can see that in the getCause method of ClientFaultConverter, you are using a StringTokenizer to iterate through different lines.
> {quote}
> StringTokenizer st = new StringTokenizer(ss, "\n");
> {quote}
> When it comes to the exception message, we have this kind of string :
> {quote}
> Caused by: beginning of the message
> end of the message
> first line of stack trace
> {quote}
> Thus this piece of code:
> {code}
> private Throwable getCause(StringTokenizer st, String firstLine) {
> // The actual exception class of the cause might be unavailable at the
> // client -> use a standard throwable to represent the cause.
> Throwable res = new Throwable(firstLine.substring(firstLine.indexOf(":") + 2));
> List<StackTraceElement> stackTraceList = new ArrayList<StackTraceElement>();
> while (st.hasMoreTokens()) {
> String oneLine = st.nextToken();
> if (oneLine.startsWith("Caused by:")) {
> Throwable nestedCause = getCause(st, oneLine);
> res.initCause(nestedCause);
> break;
> }
> stackTraceList.add(parseStackTrackLine(oneLine));
> }
> StackTraceElement[] stackTraceElement = new StackTraceElement[stackTraceList.size()];
> res.setStackTrace(stackTraceList.toArray(stackTraceElement));
> return res;
> }
> {code}
> will result in calling "parseStackTrackLine" on element "end of the message" which causes the exception.
