Hi,
I have a Camel flow which seems to be experimenting concurrency issues with
the camel-validation component. This flow is invoked twice in parallel by a
splitter.
It seems like the camel-validation component lazily-loads the XSD, when the
first request comes in.
As a consequence, when two simultaneous requests are received, it attempts
to load the XSD twice at the same time, possibly using the same
SchemaFactory, which may not be thread-safe.
Any ideas on how to tell Camel to load the XSD on initialization of the
flow, instead of on the first request?
Many thanks!
