What version of the product are you using? On what operating system?
NetBeans 7.1
AndEngine with new GLES2 (Current GitHub Version)
Windows 7 64x

Please provide any additional information below.
I could reproduce the issue on two computers. It seems since some days the 
ChangeableText class has deleted! Some examples also doesnt work after an 
actually update via github.
