Re: [ojAlgo-user] Code to reproduce strange matrix multiplication

[Anders P. <an...@op...>]

The fix is in CVS and will be included with the next release.

If you'd like to fix the problem with your current copy of ojAlgo you  
should change the MatrixUtils.EXECUTOR ExecutorService to be a  
ThreadPoolExecutor with no (very high) pool size limit.
