I try to be precise and brief but all the config excerpts and
stacktraces will make this post long, sorry.
We developed a service (using CXF and Spring) that accepts images
through MTOM. I'm pretty sure CXF/MTOM is configured correctly. Still, a
50MB JPEG sent over the wire results in ~1.5GB in the heap. Something
seems amiss but I don't understand why/what...
I see that in $java.io.tmpdir/cxf-tmp-nnnnn the MTOM attachment is
dumped. I see in the stacktrace that MTOM is used because the
MTOMDecorator class shows up. I see in the inbound message (CXF
interceptor) a MIME message with an attachment.
If the heap is too small (e.g. 800MB) the java.lang.OutOfMemoryError
occur in different places depending on available heap obviously. Examples:
- Base64 decoding (stacktrace n/a anymore)
- Arrays.copyOf
- java.awt.image.DataBufferByte.<init>
