B4J Question (Solved) NoSuchAlgorithmException with jcifs-ng SMB-Client (SMB2)

[walt61]

I'm testing @DonManfred 's SMB client (https://www.b4x.com/android/forum/threads/jcifs-ng-smb-client-smb2.104561/), both the B4A and B4J versions. B4A works fine, and so does B4J on Linux. On Windows 10 and 11 however, I'm getting the below error and have no clue what to do; the library used is jcifs-ng version 0.33. The system containing the share is a QNAP NAS.

I tried to attach the small test project but the forum seemed to think the zip file (3.3K) was empty, so I've added the code to the post as well.

Any pointers would be greatly appreciated!

I have not used the library for long time.

in my code i see that i am am using higher versions of
bcprov-jdk15on-1.61
bctls-jdk15on-1.61

This was in 2019 already
Don´t know if that´s the issue.
