Before, when two random tables are created, there was a small chance that they would have identical schemas. This caused the ImplicitMismatchCM test case to pass when it was expected to fail. Modified creation of destination table to always have a different schema from the source table.

Instead of copy paste you can use shuffle / reverse.

if(alternateSchema) {
Collections.shuffle(sqlTypes);
or
Collections.reverse(sqlTypes);
}

DBSchema(boolean autoGenerateSchema, boolean alternateSchema) { 
this(autoGenerateSchema);
if(alternateSchema) {
Collections.shuffle(this.sqlTypes);
}

Think of rewriting DBSchema(...) by calling other constructor and on top of that shuffling instead of copy paste.

We can reduced copy paste by changing public DBTable(boolean autoGenerateSchema) and public DBTable(boolean autoGenerateSchema, boolean unicode)

Example:

public DBTable(boolean autoGenerateSchema) {
 this(autoGenerateSchema, false,false);  
}
