Can't run sbt on ec2 due to lack of memory (not being able to allocate new memory)

For some reason, I can't run sbt at amazon ec2 free tier 

ubuntu@ip-xx-xx-xx-xx:~$ sbt seed
Loading /usr/share/sbt/bin/sbt-launch-lib.bash
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5550000, 715849728, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 715849728 bytes for committing reserved memory.
# An error report file with more information is saved as:

Here is top:

Note sbt seed does work at my local machine ("seed" is my custom task)

Micro instances come with 613 MB of physical memory total. You can enable swap if you need more, but keep in mind, that will be much slower.
