More Throwable information

I used spark 3.3.0, which includes netlib v2.2.1. When I ran spark on jdk17, i got a warning from yarn logs WARN InstanceBuilder$JavaBLAS: Failed to load implementation from:dev.ludovic.netlib.blas.VectorBLAS. I debug and found that the throwable message is java.lang.NoClassDefFoundError: jdk/incubator/vector/Vector, after i added jvm options--add-modules=jdk.incubator.vector to spark, this warning disappered.

https://github.com/luhenry/netlib/blob/c63517f82c888bdcf2b348d44784376610ceb7fa/blas/src/main/java/dev/ludovic/netlib/blas/InstanceBuilder.java#L72

I think this warning messages can be written in more detail.
