I confirm that the root cause of this error is likely dProtect, could you attach the Java code associated with this error?

Thank you, since this code depends on the classes StrUtils, JarEncryptor, could you attach code that I can compile to reproduce the error?

Thank you, the last bug is fixed with f9da3a0

Ok, I got it.

#3 (comment)
This problem seems to be caused by string encryption. It can work normally without string encryption.

Removing -dontpreverify in you configuration fixes the issue.

Hi @romainthomas,
Which version will be included this fix?
