JRuby crashes with -XstartOnFirstThread on carbon
-------------------------------------------------
Key: JRUBY-2510
URL:
http://jira.codehaus.org/browse/JRUBY-2510 Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.1.1
Environment: carbon
Reporter: Ketan Padegaonkar
To reproduce this bug, start jruby as: jruby -J-XstartOnFirstThread
Wait a while as jruby crashes with no warnings or errors printed on the console.
From
http://www.eclipse.org/swt/faq.php#carbonapp:If you run a Java application that uses Carbon via JNI, the application is not registered with the OS as a 'normal' UI application. As a consequence, it has no entry in the dock and it cannot be activated. AWT (or Swing) based applications don't have this problem because they seem to use undocumented SPI to register themselves.
To work around this problem you'll have to pass the -XstartOnFirstThread option to the java executable as follow:
java -XstartOnFirstThread -cp swt.jar:. ControlExample
