Java verify error

Hi!
I have just installed the latest SNAP version 9.0 on a Centos machine.
We erased the previous version and installed the new one.
However, running PixEx I get the error attached at the end of the message.
I tried the same xml graph with SNAP 9 on a windows machine and it works fine.
Thank you for your support

Thanks for you report.
I’ve found a similar error report here:
java.lang.VerifyError with JWT and Jackson · Issue #367 · auth0/java-jwt (github.com)

The reason there is that classes (different version) are located on the classpath two times.
But this is not the case for SNAP.
The jackson classes are only found one time in the project source code and dependencies.

Could you try to use the ‘-noverify’ option.
Actually, the verifier is already disabled by the ‘-Xverify:none’ option, at least for SNAP Desktop.
If you see the error in the GUI then please, try:
Add the ‘-noverify’ option to the snap.conf (etc folder of installation directory) tile in the default_options line
Prepend it with ‘-J’.
So, the start of the line would look like:
default_options="--branding snap --locale en_GB -J-XX:+AggressiveOpts -J-Xverify:none -J-noverify -J-Xms256M

If you see the error when you execute gpt, then please edit the gpt.vmoptions file in the bin folder of the installation directory.
Add a new line with
-Xverify:none
or
-noverify
or both.

Thank you @marpet,
I will try!
