Specification excerpt:
======================
--------- J2SE API spec v.1.5 ---------
...
The following is true of a default BaseRowSet instance:
. . .
In other words, when a default RowSet object is created, it is as if the following BaseRowSet methods had been called:
. . .
     setConcurrency(ResultSet.CONCUR_READ_ONLY);
. . .
===

public int getConcurrency()
                   throws java.sql.SQLException
Returns the concurrency for this JDBC RowSet. The concurrency is initially
determined by the statement that created the JDBC RowSet. The JDBC
RowSet can call the method setConcurrency at any time to change its
concurrency. The default is CONCUR_UPDATABLE.

For disconnected JDBC RowSet implementations such as the CachedRowSet
 that operate in a disconnected environment the SyncFactory SPIs and
SyncProvider mechanisms offer complimentary concurrency options. The
 options described below are pertinant only to connected JDBC RowSet's
 such as the JdbcRowSet.

Returns:
the concurrency type for this JDBC RowSet object, which must be one of the
following: ResultSet.CONCUR_READ_ONLY or ResultSet.CONCUR_UPDATABLE
Throws:
java.sql.SQLException - if an error occurs determinig set concurrency of the
JDBC RowSetl or if no concurrency has been set.

Problem description
===================
BaseRowSet describe different default concurrency property value.
CONCUR_READ_ONLY at the class definition and CONCUR_UPDATABLE at
the getConcurrency() method specification.

Also in the getConcurrency() spec:
 ("Throws:
  java.sql.SQLException -
  if an error occurs determinig set concurrency of the JDBC RowSetl
  or if no concurrency has been set.")

"or if no concurrency has been set." is redundant since default BaseRowSet
is initialized with setConcurrency(ResultSet.CONCUR_READ_ONLY) as spec says.
