Summary:
The Java runtime does not detect clipboard changes if they are made by a background application. The workaround is to switch to another application and back to the Java application so that the clipboard gets updated.

Steps to Reproduce:
1. While using a Java-based application (e.g. the Oxygen XML editor), copy some text.
2. Have a background application modify the clipboard (e.g. TextExpander).
3. Without leaving the Java-based application, paste the clipboard contents.

Expected Results:
The clipboard as modified by the background application is pasted.

Actual Results:
The contents copied from within the Java-based application is pasted rather than what was placed on the clipboard by the background application. If using TextExpander, for example, inserting a snippet will have the result of pasting the Java application's last clipboard state rather than the snippet contents.
