Problem description

After Updating from driver version from 12.2.0 to 12.6.1, some SQL queries throw NoClassDefFoundError: com/microsoft/sqlserver/jdbc/StreamInfo. Inspecting the JARs of the driver versions, this StreamInfo class exists in 12.2.0 but not on 12.6.1 anymore!

Expected behavior

No change of classes or at least description in driver release notes about this change and how to replace old behaviour.

Actual behavior

See error message below.

Are you sure you were running 12.6.1? Your line numbers don't line up with code from any release tags.

StreamInfo appears to be in 12.6.1 but has been deleted in PR #2251, which would only put it in 12.7.0. But again, your stack's line numbers don't align with the code from that tag, either.
https://github.com/microsoft/mssql-jdbc/blob/v12.7.0/src/main/java/com/microsoft/sqlserver/jdbc/SQLServerStatement.java#L1636

Are you running a jar you've built yourself?

Hi @JDBC-0,

We'll be closing this issue in a few days if there is no further reply.

[JDBC-0]

It was 12.6.1 .... we reinstalled the driver and then the error didn't occured anymore. Probably corrupt JAR file.
If 12.7.0 will remove StreamInfo, will this be binary compatible or an incompatible change?

[David-Engel]

StreamInfo wasn't a public class, so it should remain compatible.
