> JDK9: IgniteUtils classLoaderUrls() JDK9 bug
> --------------------------------------------
>
> Key: IGNITE-8146
> URL: https://issues.apache.org/jira/browse/IGNITE-8146
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 2.4
> Reporter: Sujit Kumar Mahapatra
> Assignee: Taras Ledkov
> Priority: Trivial
> Labels: jdk9
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> Reporting a probable miss that breaks JDK9 compatibility.
> As part of [this
> commit|https://github.com/apache/ignite/commit/ee2a6f7c3f2e3c9bd8dc61c8dbdf171e933d9481#diff-309ab4ef2fc61d6b2570d390acfb9bd6]

> below lines will throw *ClassCastException* in JDK9 during runtime.
> _return ((URLClassLoader)urlClsLdrField.get(clsLdr)).getURLs();_
>
> Here, _urlClsLdrField.get(clsLdr)_ return an object of type
> "___java.base/jdk.internal.loader.URLClassPath_" which can't be cast to
> "_URLClassLoader"._
>
> The fix seems to be to introduce another reflection call to invoke _getURLs_
> method of the internal _URLClassPath_ class.
