Hang at Initialize UI

[4restM]

Heya folks. Having some issues running the application on mac. It is currently hanging after open .jar file. Have tried multiple versions, 6.06.1 & 6.07.7 & 6.07.8. Have also reinstalled java JRE and JDK multiple times and restarted.

My java log is as follows.

21:33:17.733 INFO main Main:140 Starting PCGen v6.07.08 21:33:17.875 INFO main LanguageBundle:134 Initialising language bundle with locale en_US. 21:33:34.341 SEVERE main Main:544 Uncaught error - ignoring java.lang.NoClassDefFoundError: com/apple/eawt/AboutHandler at pcgen.gui2.PCGenUIManager.initializeGUI(PCGenUIManager.java:52) at pcgen.system.Main.startupWithGUI(Main.java:258) at pcgen.system.Main.main(Main.java:161) Caused by: java.lang.ClassNotFoundException: com.apple.eawt.AboutHandler at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(Unknown Source) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(Unknown Source) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) ... 3 more

To clarify it hangs at initializing UI

I have this same issue.

I also have this issue. Perhaps related to having newer versions of the JDK.

I have a fresh install, with a brand-new install of JDK 10. Hangs at "Initializing UI".

If there is a specific version that this is know to work with (or not work with), is that documented anywhere? The only note I see in the installation instructions looks very out of date, and says "you need at least this version..." If it only works with legacy Java, that would be good to know. : )

i have an old version of this running on legacy Java on an old mac.

PCGen 6.03.06 Java 7 version 67 (build 1.7.0_67-b01)

[coyoteconscious]

After removing all of JDK 10 (googled it), I installed Java 8 Update 181 and that seems to work.

Might want to add a note in the documentation about which Java works.

I found this problem with Java 10 on Mac. Simple change in PCGenUIManager got me passed

The line

// Don't start macOS GUI if we're on Java 9 since it doesn't work.
if (SystemUtils.IS_OS_MAC_OSX && (System.getProperty("java.runtime.version").charAt(0) != '9'))

Wouldn't handle newer versions of Java beyond java 9... This fixes it..

// Don't start macOS GUI if we're on Java 9 or later since it won't work.
if (SystemUtils.IS_OS_MAC_OSX &&
    (Integer.valueOf(System.getProperty("java.runtime.version").split("\\.")[0]) < 9))
{

And will account for newer versions of java until the MacGUIHandler can be removed or updated.
Can some one add this to master? Or would you like me to PR?

Just started playing Pathfinder and PCGen saves sooooo much time. :) I dig it!

This is already handled in PR https://github.com/PCGen/pcgen/pull/4169#pullrequestreview-147165055 that will fix the MacGUIHandler.
