Hi,
Yes, it looks like this doesn't affect H2. Maybe it is related to the
changes to the LZF compressor in MapDB? My test case:
byte[] data =
StringUtils.convertHexToBytes("000000ef76fa135e7d216e829a53845a983469ac1e4edb6120b79667d667e7d4f8560101010100000022bf456901000000230000002102123eeaa90e2f5786ce028e60ec03702706dadecee373a90b09b88a99cc668f46ac3358c8ea6433279c678846fb6e06eeccd82e2fe888f2ac203476d3918cd405790100000038ffffff9e000000be438253be43825301000000109bf45901000000230000002102123eeaa90e2f5786ce028e60ec03702706dadecee373a90b09b88a99cc668f46ac38bf80f10129594a7e949cc43c3bd6f8670ba5ab59874305f6839406738a9cf90100000038ffffff9e00000081bd175381bd1753");
CompressLZF lzf = new CompressLZF();
byte[] out = new byte[data.length];
int len = lzf.compress(data, data.length, out, 0);
byte[] test = new byte[data.length];
lzf.expand(out, 0, len, test, 0, data.length);
System.out.println(StringUtils.convertBytesToHex(test));
System.out.println(Arrays.hashCode(data));
System.out.println(Arrays.hashCode(test));
Regards,
Thomas
