<p>I see many warnings when I build Apache Derby's code and
javadoc with Open JDK build 20-ea+27-2213. In particular, I see
a number of warnings introduced by the following change:<br>
<br>
- JDK-8294241: Deprecate URL public constructors <br>
<br>
I naively tried to fix these warnings by changing instances of<br>
<br>

<pre> new URL(urlString)</pre>
<p><br>
to<br>
<br>
</p>
<pre> (new URI(urlString)).toURL()</pre>

Unfortunately, this breaks the Derby code. When I test Derby, I
see errors like the following:<br>
<br>
java.lang.IllegalArgumentException: URI is not absolute<br>
at java.base/java.net.URL.of(URL.java:854)<br>
at java.base/java.net.URI.toURL(URI.java:1144)<br>
at
org.apache.derby.impl.store.raw.RawStore.backup(RawStore.java:641)<br>
<br>
Can you give me advice about the best way to workaround the
deprecation of the public URL constructors? I am looking for a
solution which handles relative URL strings.<br>

URL::toURL is specified to throw if the URI is not absolute although
the IAE may be a bit surprising as there isn't any arguments.<br>
<br>
Can you give an example of the "relative URL strings" so we can at
least see which URI scheme this is.<br>
