ByteInputStream and spim version

Thank you for sharing your amazing work!

I tried to run it and found these two issues: 1.

what spim version you were using? Are there any alternative to get rid of the ByteInputStream dependencies?

[abcdabcd987]

I think I must have mistakenly used ByteInputStream. I'm not sure what's the alternative since I haven't used Java for a long time. Anyway, it only has to be a derived class of InputStream. Maybe try BufferedInputStream?

spim we used in this class was: https://bitbucket.org/xjia/statspim

thank you for your reply!

I just tried the statspim and it takes forever to run the testcase1 in the Finaltest section. Also, for the SSA constructor/destructor test, they are not working because of the null pointer issues.

All other tests are working fine except for some locations issues.

Yeah I remember statspim being buggy. I remember I couldn't run statspim on Ubuntu 16.04. I can't remember what is wrong exactly, but maybe like you say, running forever (or I suspect it doesn't run at all. Check CPU usage). Then I switched back to Ubuntu 14.04, and it worked.

I'm not sure about the null pointer issues. I should have passed all the tests. But maybe there are some bugs I didn't discover.
