My snap always point out error about java

[sky_moon]

my snap always point out error about java. For example , when i run the process (mosaicing), i met the error about java as followed.

Can you tell a bit more about your processing, please.
What kind of data do you want to mosaic? How many products?
Also helpful would be the details shown after you click on ‘Show Details’. Even better would be if you attach the log file mentioned in the message.
Otherwise it is nearly impossible to find the cause the the error.

The data which i used were sentinel1-A-EW-GRDM. There are three products.
these products were processed by Range-Dopller terrain correction and the size up to 2.1G . the picture of ‘Show Details’ is as followed.

Can you provide me these three products? I send you a PM with the information where you can upload the data.
Thanks.

Please, help me solve it

Thank you very much

The problem is already known:

SNAP exception errors on update

Hello, Unfortunatelly, the gdal library of SNAP is not working on 32bit. Furthermore, this exception is affecting also some SNAP functionalities, like GPT. In this moment, the only solution is to uninstall SNAP, and to install it again without the S2TBX module (after that you can even update it, but remember not to install the S2TBX). We are working on a solution that will be available in the next release. Thank you for your understanding.

Thank you for your explanation.
I will wait for next release
One more thing, I got problem with sen2cor 2.3.1 as using it for atmosphere correction. It seems that it is just supported by 64 bit. while my platform is 32 bit. You have any way to solve my problem ? Any old version of sen2cor that is compatible with 32 bit platform and Snap ?

[baotran1308]

You mean S2 TBX modul is Sentinel 2 Toolbox ?
I am new with SNAP, so, I have some confusion with it. So sorry

Regarding sen2cor see this post:

SEN2COR tool

I think there never was a 32bit version of sen2cor. But @umwilm can correct me. Best would be to update your system. A 32Bit system can not manage more than 4GB of RAM. And this is often not sufficient for processing S2 data.

S2TBX module is the Sentinel-2 Toolbox, yes.
and please see here:

SNAP exception errors on update

It could be a workaround to delete the gdal modules manually. They are named: org-esa-s2tbx-s2tbx-gdal-reader.jar and org-esa-s2tbx-s2tbx-gdal-reader-ui.jar You can find them either in C:\Users\USER_NAME\AppData\Roaming\SNAP\modules or on Unix /home/USER_NAME/.snap/system/modules Delete both files. After starting SNAP you will be asked that if you want to disable these modules. Answer yes.

This might be a workaround. Uninstallation of S2TBX is then not necessary.

I will try

The problem with the StackOverflowError shall be fixed with the next release. I don’t know yet, when it will be available.
