[jira] [Commented] (NETBEANS-5500) URLStreamFactory registration
violates JDK9+ reflection restrictions
[ https://issues.apache.org/jira/browse/NETBEANS-5500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17347791#comment-17347791 ]
Rangi Keen commented on NETBEANS-5500:
--------------------------------------
JDK 16 will throw a runtime exception and JDK 17 will no longer allow this reflective access. See [A peek into Java 17: Continuing the drive to encapsulate the Java runtime internals|https://blogs.oracle.com/javamagazine/java-runtime-encapsulation-internals#anchor_7] for details.

> Key: NETBEANS-5500
> URL: https://issues.apache.org/jira/browse/NETBEANS-5500
> Project: NetBeans
> Issue Type: Bug
> Components: platform - Module System
> Affects Versions: 9.0
> Reporter: Jaroslav Tulach
> Assignee: Svatopluk Dedic
> Priority: Major
> Labels: VSNetBeans
> Fix For: Next
>
>
> If you run NetBeans on JDK9+ you'll see:
> {code:java}
> WARNING: An illegal reflective access operation has occurred
> WARNING: Illegal reflective access by org.netbeans.ProxyURLStreamHandlerFactory (file:/netbeans/nbbuild/netbeans/platform/lib/boot.jar) to field java.net.URL.handler
> WARNING: Please consider reporting this to the maintainers of org.netbeans.ProxyURLStreamHandlerFactory
> WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
> WARNING: All illegal access operations will be denied in a future release {code}
> There is a new API that one can use to register (most of) the factories on JDK9+: [https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/net/spi/URLStreamHandlerProvider.html]
> We should use it as once the JDK is going to ban the illegal access operations and then it is better to be ready.
