IndelRealigner Crashing, Java Fatal Error

Hello GATK,

I am receiving the following error when running this script:

I am running GATK 3.8, nightly build from 09/18/2017

As for java:
openjdk version "1.8.0_144"
OpenJDK Runtime Environment (build 1.8.0_144-b01)
OpenJDK 64-Bit Server VM (build 25.144-b01, mixed mode)

I am trying to use 3.8 because 3.7 keeps crashing at HaplotypeCaller. I am now trying 3.7 using the flag --pair_hmm_implementation LOGLESS_CACHING, as this was a suggestion from my server administrator. She was also running into problems with HaplotypeCaller and this fixed her issue.
