Possible issue with multi-thread native libraries

[avulanov]

Apache Spark crashes when using native BLAS/Lapack Win x64 precompiled libraries (from here http://sourceforge.net/projects/openblas/files/v0.2.11/OpenBLAS-v0.2.11-Win64-int64.zip/download). If I compile them single-threaded then everything is fine. It seems that the same issue is observed on Linux. For more details, please look at my issue in Spark issue tracker: https://issues.apache.org/jira/browse/SPARK-3403

that sounds like a problem with your native libraries, not in netlib-java.

I recommend using a BLAS supplied by your chip manufacturer, and if you're really keen try to isolate the problem in OpenBLAS and submit a bug report to them.
