After migrating to pljava1.6 we see quite often
java.nio.charset.MalformedInputException: Input length = 1 error
even when function called do not deal with any streams in an obvious way (there might be small chance some properties are read, to be checked).
All of these functions worked ok in 1.5 - do you have any hint by any chance why this could happen?
Were there any changes in 1.6 that could cause it?

It's not 100% reproducible and hard to pinpoint esp. we get it on postgres-xl/tbase
Setting client_encoding does not necessarily help.

Thanks
