SNAP Java "Concurrent Modification Exception" internal error during radar image processing

I’m currently using version 7.0 of SNAP, updated to last version.
I’m working on interferometry with COSMO-SkyMed Himage data.
I get constantly the ConcurrentModificationException error in every process.
I have this error since version 5.0 of SNAP with all kind of radar images and in different hardware (processors Intel and AMD, memory 6 to 32 Gb RAM) and software (Windows XP, 7 and 10) setups.
Here is the report:

Is there a solution? Are the results ok even though the error in present?
Thanks in advance.
