Spring Integration's FileWritingMessageHandler uses a .writing file
while it's in the process of writing a message to disk and then
performs a rename (depending on the OS and filesystem this may or may
not be atommic) to create the .msg file. Prior to this commit the
test was finding the temporary .writing files and examining them. This
could lead to a FileNotFoundException being thrown as the temporary
file was deleted while the test was trying to read its contents.
This commit updates the test to only look for files with a .msg suffix
Fixes gh-2428
Previously, SampleIntegrationParentApplicationTests assumed that when
an output file existed on disk its contents would have been written
in their entirety. This assumption does not hold true and causes the
test to fail intermittently as it incorrectly determines that the test
has produced no output.
This commit updates the test to wait for up to 30 seconds for the
output files to appear on disk and for the expected content to be
found in one of those files. If the files exist but do not
contain the expected content the test will keep trying until it does
or until too much time as elapsed.
Fixes gh-2380
When there are parent contexts we already had a strategy for registering
the actuator endpoints, but not the regular JMX or Integration MBeans.
This chnage makes the autoconfigs for JMX aware of the parent context.
Also adds a sample with a parent context.
