Issue Links

• is blocked by: DERBY-2711 If large blob is updated after InputStream is fetched (using getBinaryStream), the stream continues to point ot old data
• is blocked by: DERBY-2712 If large clob is updated after Reader. the reader continues to point to old data
• is part of: DERBY-1341 LOB set method(s) are currently no supported, but part of the Java 1.4 JDBC interface
• relates to: DERBY-2818 Rewrite ClobUpdatableReader constructors
