Description

The getURI code in solrcas (SolrCASConsumer) has the code:

if (!uri.isAbsolute())
uri = UriUtils.create(new StringBuilder(FILEPATH).append(getContext().getDataPath()).
append("/").append(path.replace(FILEPATH, EMPTY_STRING)).toString()); // this supports relative file paths

On Windows, the getContext().getDataPath() returned "C:\blah\blah", so the string passed to UriUtils.create was something like:

file://C:\a\b\c\Solrcas/src/test/resources/org/apache/uima/solrcas/

The "backslash" char is "escaped" by the create method, since it's not a valid in URIs, giving:

file://C:%5Ca%5Cb%5Cc%5CSolrcas/src/test/resources/org/apache/uima/solrcas/

When this URI is given to new File(...) this causes an error to be thrown:

java.lang.IllegalArgumentException: URI has an authority component

It thinks there's an authority component because of the colon character. It seems the right thing to do for this kind of an "absolute" URI on Windows, if it starts with a C: or something similar, is to prefix this with another "/" char, so the string looks like

file:///C:\a\b\c\Solrcas/src/test/resources/org/apache/uima/solrcas/

e.g., file: followed by 3 slashes: ///
