I am getting this error message every time I start my RAD. I try to solve but changing -XX:MaxPermSize from 128 to 256M and -Xmx from 1024 to 512m. My eclipse.ini is below. I guess the most relevant information are the memory of my VM is 4GB and I don't have Java_Home environment variable and I can't change both. But everything runs as expected in RAD.
