[THREDDS #ZIZ-818863]: Thredds inflation of data



I have a question.
Is the issue the default_file_buffersize in IO.java in general, or is it
specifically the IO.copy() call in H5tiledLayoutBB?

> Hi Martyn,

> Here is a recent SNAPSHOT build of toolsUI that includes the fix:

> 
> Alternatively, here is the TDS build from the same commit:
> https://artifacts.unidata.ucar.edu/repository/unidata-snapshots/edu/ucar/tds/4.6.11-SNAPSHOT/tds-4.6.11-20171119.194513-36.war
> Make sure to rename it to "thredds.war" before deploying it in Tomcat.
