Hello,
I work on TOS 4.2.1/ TOS 5.2.1 and I had this problem since a couple of days without touching at any settings. the program shows this message everytime" Erreurs de génération.
Erreurs lors de lexécution du générateur {0} sur le projet {1}'.
java.lang.NullPointerException". I work on JDK 8 update 91 on windows XP OS.
Here is my log file

Install JDK 7.
If you're on Windows, modify the .BAT to something like: -
C:\Talend\TOS_DI-20141207_1530-V5.6.1\TOS_DI-win-x86_64.exe -vm "C:\Program Files\Java\jre7\bin"
or something similar for Unix/Linux.
If you've got multiple Java versions, you need tell Talend which to use, if it is not to use the default. It sounds like you now have both 7 & 8 installed.
As you're on windows, it is a .BAT file that you're using to start Talend, TOS_DI-win-x86_64.bat, for example. . You can modify this file, to specify the Java version.
