Eclipse Oxygen's Text Font setting and those derived from it are not respected

I installed the latest Eclipse IDE for C/C++ Developers (Windows 64-bit) recently.
When changing Text Font to my personal preference I realized that this setting and those derived from it (C/C++ Editor Text font, C/C++ Build Console Text Font, Structured Text Editor Text Font) are not respected in Generic Text Editor, Text Editor, C/C++ Editor, XML Editor.
Funny thing is: If I Reset Text Font the font name in the Preview below is empty(!), just the font size is displayed there and the text preview's font is the font that's used in all the editors mentioned above.
Is this a (known?) bug or what am I missing here?
UPDATE
Preferences:
This is NOT Courier New:
I downloaded and extracted the package once again and now the font preferences work as usual.

Change Font Colors and Style for TeXlipse Only in Eclipse

Having just installed the TeXlipse plugin onto Eclipse 4.5, I am having a difficulty figuring out whether there is a way to change how Eclipse highlights the TeX code. At the moment, I am using the dark theme for Eclipse and the colors (dark blue, purple, etc) it chooses for TeX are hard to see. I would like, however, to leave all the styling for Java code as is.
Go to Window > Preferences > Texlipse > Editor > Syntax Highlighting, there you can change colors and font type.

Aptana Studio Eclipse IDE messes up color theme

Before I installed the Aptana Studio IDE for Eclipse my theme was set to "Dark" and the editors to "Sublime".
After I installed Aptana all editors appeared in a white background color.
I know that Aptana has it's on settings for that but I want to separate the settings of Aptana and Eclipse. So Eclipse's settings should apply to all "normal" editors and the Aptana settings should only apply to its on editors.
So right now, everything is white. And it only changes in black when I click "Apply to all (non-studio) editors" (In the Aptana settings).
But I don't want that!
I want to have my "normal" java editors like before and the Aptana editors should look different. But nothing will change if I set the settings in "preferences -> appearence -> color theme". Can anyone help me?

How to change font (family) of comments in Eclipse?

How to change font (font family/name) of comments in Eclipse? I can do it in NetBeans, but is it even possible in Eclipse? In Window -> Preferences -> C/C++ -> Editor -> Syntax Coloring I can change only the colour of the fonts, but I would like to change also the font itself.
(I'm using Eclipse Juno.)
Try Window->Preferences->General->Appearance->Colors and Fonts. I'm using Eclipse Kepler, so I'm not sure this is available in Juno.
