> Sybase has the wonderful characteristic of truncating trailing zeros in VARBINARY columns.
> So If I set a byte array with values: 1, 2, 3, 4, 5, 0, 0, 0
> Then I get back a byte array with values: 1, 2, 3, 4, 5
> Xid global txids and branch qualifiers can have trailing zeros since they can become corrupt after storing and retrieving in the database.
> Solution is to introduce a flag "usingTrailingByte" on the pm config. If true then a non zero byte will always be appended to the byte[] before storing and removed on retrieval.
> This flag should be true for sybase config and false for others.
