JAVA_TOOL_OPTIONS value breaks otherwise working execution

[Guillermo G. de Garibay]

The value for JAVA_TOOL_OPTIONS set by upstart breaks the window menu and window focus of a GraphicsProgram built with the ACM Java Libraries.

When JAVA_TOOL_OPTIONS is unset, everything works perfectly as expected.

If I don't unset the variable, my window is unable to keep window-manager focus and loses the window menu (nor window menu, neither global menu). This results in the program being unable to capture any mouse or keyboard events.

The terminal output that I get is the following:

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
Exception in thread "AWT-XAWT" java.lang.NoClassDefFoundError: com/jarego/jayatana/FeatureManager
