Import with GZIP compression enabled fails on Resin

While attempting an import with the GZIP compression enabled, the following exception occurred running on Resin. The data was exported from a JIRA instance running on Tomcat with the GZIP compression enabled.

If GZIP compression is disabled in the original export - the data can be successfully imported.

The stacktrace is:

java.lang.NullPointerException
