#4068 NoSuchMethodException in OSXAdapter.java

[Kohei Nozaki]

Hello,

After upgrading jEdit to 5.5.0, I've started getting the following error at every launching (I haven't seen any problem which caused by this though)

java.lang.NoSuchMethodException: com.apple.eawt.Application.addApplicationListener(com.apple.eawt.ApplicationListener)

jEdit version: 5.5.0
platform: OSX 10.12.6
Java version: Oracle Java 9.0.4
step to reproduce: Simply launch jEdit with MacOSXPlugin enabled, and you'll see "7 error(s)" on the status bar

Thanks,
Kohei

The same happens with recent OpenJDK 11 on macOS 10.13.6, see the included log.

Java 9 has official discontinued some old macOS desktop features. Instead there are regular JDK operations for that. See also:

This should long be fixed already in the newer Mac OS Support 1.5 plugin, which will also be shipped with jEdit 5.7.0, but can also manually be installed through the plugin manager.
