Eclipse (ADT) crash Failed to write core dump. Core dumps have been disabled

I found my problem here: how to fix “Failed to write core dump. Core dumps have been disabled” error while running java and here: Eclipse crashing on startup and here: Eclipse continue crash
This is the problem:

# A fatal error has been detected by the Java Runtime Environment:

I did this: To enable core dumping, try "ulimit -c unlimited" before starting Java again and also not help;

To solve this issue, try to put this line (slightly different from -Dorg...)
