MSSQL client hides the cause of an error

[DavideD]

Version

5.1.2

Context

When the MSSQL client encounters an unsupported data type (e.g. XML), DataType.decodeTypeInfo() throws an UnsupportedOperationException:

  // DataType.java — default implementation
  public TypeInfo decodeTypeInfo(ByteBuf byteBuf) {
      throw new UnsupportedOperationException("Unable to decode typeInfo for " + name());
  }

In previous versions (5.0.x), this exception was propagated to the caller, allowing downstream libraries to catch it and provide a meaningful error message.

Since 5.1.0, the exception is no longer propagated. The only exception thrown is ClosedConnectionException

@DavideD such connection errors are now reported through io.vertx.sqlclient.SqlConnection#exceptionHandler

Does that work for you?

[DavideD]

Mmmh... OK, I will test it and let you know

[DavideD]

Yep, that works.

Thanks @tsegismont

Reopened and filed #1672 , because this is not specific to MSSQL
