Out of memory when ResourceProvider throws an IIOException

#27105

We implemented a custom ResourceProvider that load images then resize them to fit our required size

In some special use case, when resize failed a javax.imageio.IIOException is thrown then it causes PD4ML to run into Out Of Memory (Tested with JVM 2Gb)

It seems due to an infinite loop

Hi,
do you have some news ?

Thanks

#29944

How big is the original image (dimensions, file size)? What are the dimensions after the resizing?

#29945

Problem is not with the resize part: in fact the resize failed because source is not found for example. But the problem occurs after that: when our custom code throws an exception, then PD4ML code runs into out of memory

#29946

Please check my email reply.
