jEdit 5.3pre1 does no longer work with early access releases of JDK9. Last known good
is 1.9.0-ea-b52. Since there have been changes to class and resource loading in JDK9,
this is most likely going to be a permanent problem and requires changes in jEdit.
The most severe problem seems to be with icon loading, especially on the Event Dispatch
Thread (EDT), aka "AWT-EventQueue-0". If this takes time to fix properly, could someone
please implement some workaround to get jEdit 5.3pre1 up and running again (sans icons)?
Here are some of the exceptions:

Java 1.9 requires a service provider to register an URL stream handler. See [java.net.spi.URLStreamHandlerProvider](http://download.java.net/jdk9/docs/api/java/net/spi/URLStreamHandlerProvider.html)
and [bug #8064924](https://bugs.openjdk.java.net/browse/JDK-8064924) as well as [changeset
11480:a4e47f145dda](http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/a4e47f145dda).

I am confused about the 2nd attachment, is it really a one-liner?

I just installed jdk 9: jdk-9-ea-bin-b64-windows-x64-13_may_2015.tar.gz

Nothing was done to jEdit to fix this issue, so since your newer early access works,
I can assume this was an issue that was fixed in JDK and we can close this ticket,
unless someone else can reproduce it?

Yes, it is a one-liner. It's just a direct referral mechanism. By putting that one
liner (2nd file) into the special META-INF folder, you tell Java where to find the
provider (1st file) and the provider supplies an instance of the actual URL stream
handler for "jeditresource:". This is probably faster than the old way of searching
the URL stream handler among all files on the class path.

Apparently somebody got cold feet and Chris Hegarty put some old code back in, see [bug #8075139](https://bugs.openjdk.java.net/browse/JDK-8075139). Both the new service provider mechanism and the old way of searching through classes work with Java 1.9.0-ea-b64. |

You might still want to use the new service provider mechanism since it eliminates the need to search all classes for the "jeditresource:" URL stream handler and might improve startup time. It will also be compatible with modules, which is why they did the change in the first place. Your call. |

I'll test the addition of the META-INF file as an optimization. |

URLStreamHandlerProvider is new in java9, so we can't compile it with java7, which
is current minimal version.
