NPE at lucee.runtime.spooler.SpoolerEngineImpl.getFile()

Description

After upgrading to Lucee 5.2.4.37, we started receiving hundreds of these errors in lucee-stderr.XXXX-XX-XX.log:

Exception in thread "Thread-NNNNN" java.lang.NullPointerException
at lucee.runtime.spooler.SpoolerEngineImpl.getFile(SpoolerEngineImpl.java:254)
at lucee.runtime.spooler.SpoolerEngineImpl.store(SpoolerEngineImpl.java:223)
at lucee.runtime.spooler.SpoolerEngineImpl.execute(SpoolerEngineImpl.java:625)
at lucee.runtime.spooler.SpoolerEngineImpl$TaskThread.run(SpoolerEngineImpl.java:536)

The servers this is happening on eahc send out ~50k emails/day (CFMAIL), and while most emails are still being delivered, a great many are falling through the cracks.

Environment

Windows Server 2016 64-bit
Tomcat/8.5.23
Java 1.8.0_152

fyi, to replicate (5.2.6.35-SNAPSHOT):

i ran one of your tests to create a "bad email" that shows up in the scheduler https://github.com/lucee/Lucee/blob/9d9aff960e6f3eb68ac8d817291c00bc1015b51d/test/tickets/LDEV1537/test2.cfm

then attempted to execute the "failed" mail task, to which I get this exact same NPE exception
pseudo code:

most likely a concurrency issue that is hard to reproduce, could only happen in a certain JVM implementation.
ATM there are 2 objects that could cause the issue, with 5.2.6.16-SNAPSHOT we will change the code, so the stacktrace will show us which object exatly causes this.
Will inform here asap version is avialble for testing.
