Not clear how this is a bug with Eclipse. I suggest you open a bug report with the developers of your decompiler plug-in.
This is probably not Eclipse, but I will send it to JDT just in case.
That's indeed a bug in a third-party plug-in (probably JD-Eclipse). Please report the bug against that plug-in. Apart from deinstalling JD-Eclipse, maybe you can also resolve the situation in the "File Associations" preference page by setting the default editor for "*.class" to "Class File Viewer".
