In [1] I see the following code:

! if (!Files.isDirectory(cryptoPolicyPath)
! || !Files.isReadable(cryptoPolicyPath)) {
! throw new SecurityException(
! "Can't read cryptographic policy directory: " +
! cryptoPolicyProperty);
! }

I would try to find out what "cryptoPolicyPath" is, what file is expected, and
put the expected file at the right place in the run script (in the <vfs> node +
boot modules).

[1] jdk/src/java.base/share/classes/javax/crypto/JceSecurity.java.template

Regards,

Sebastian
