----------------------------------
Summary: StringIndexOutOfBoundsException during construction of
failover request
Key: CXF-7210
URL: https://issues.apache.org/jira/browse/CXF-7210
Project: CXF
Issue Type: Bug
Components: JAX-RS
Reporter: Sebastian Hoß
Priority: Trivial
In {{AbstractClient}} we [have the
following|https://github.com/apache/cxf/blob/master/rt/rs/client/src/main/java/org/apache/cxf/jaxrs/client/AbstractClient.java#L650]:
{code}
UriBuilder builder = new UriBuilderImpl().uri(newBaseURI);
String basePath = reqURIPath.startsWith(baseURIPath) ? baseURIPath :
getBaseURI().getRawPath();
builder.path(reqURIPath.equals(basePath) ? "" :
reqURIPath.substring(basePath.length()));
{code}
This covers two out of three potential cases:
1) {{baseURIPath}} and {{reqURIPath}} have the same value which will result in
only the base path being added to the builder.
2) {{baseURIPath}} and {{reqURIPath}} have a different value in which case the
builder will get the base path and and everything from the request path that is
not already included in the base path.
What's missing (and what is causing the exception below) is that the base path
might be longer than the request path in which case
{{reqURIPath.substring(basePath.length())}} throws the following stack trace:
{code}
