We are using Eclipse Kepler (Build id: 20130614-0229) with the JDK 1.7_25. One of our projects requires Java FX. Since it is not part of the standard system library, we are adding it in Eclipse to the JRE Definition as a system library (Preferences -> Java -> Installed JREs -> Edit).
The Problem is that this path gets reset when we restart Eclipse and hence compile errors appear in the Java FX Project. Does anyone know, how to to fix this issue, or what plugin could cause this behavior? (We are using the Attlassian Connector Plugin, the Google and GWT Plugin and Subversive Connectors Plugin).
Installing e(fx)clipse and adding the JAVA FX SDK Library to the build path of the project works as a workaround.
