getBytes throws AEADBadTagException

[xraw]

While encryption / decryption works on 5.x and 6.x series, on a S7 with 7.x I get this exception while decoding with getBytes. Data amount less than 32K works without issues, but whenever I try with larger data I get this (see below). Then I tried to write chunked byte buffers (split a large byte buffer into multiple 32K buffers) but the problem remains the same.
