This looks good to me, any reason why you didn't also add USE_JDK_DEFLATER while you were there? For other folks, this is related to the following issues:

• Possible core dumps due to Intel's gkl samtools/htsjdk#1420
• Consistent SEGFAULT in CollectGcBiasMetricsTest broadinstitute/picard#1383
• Consistent Segfault in deflater code IntelLabs/GKL#101

I think that's what I did? If the Boolean is true, the JDK inflater is used, if the Boolean is false, the Intel inflater (if available) is used. If no Boolean is provided, the Picard default is used.
