DB2 FOR LUW / DB2FORLUW / 950 - DB2

An application using the JDBC/JCC driver will hang when calling 
the streaming methods: 
 
PreparedStatement.getCharacterStream(int, Reader) 
OR 
PreparedStatement.setCharacterStream(int, Reader, -1) 
 
A javacore from the hanging application may be similar to the 
function stack below: 
 
java.lang.Thread.State: RUNNABLE 
at 
java.nio.charset.CharsetEncoder.encode(CharsetEncoder.java:544) 
at com.ibm.db2.jcc.t4.ib.a(ib.java:257) 
at com.ibm.db2.jcc.t4.lb.a(lb.java:1635) 
at com.ibm.db2.jcc.t4.lb.a(lb.java:181) 
at com.ibm.db2.jcc.t4.vb.a(vb.java:175) 
 
 
This issue is not affected by CPU load and occurs when streaming 
is used for large CLOBs.  For example if MY_DATA was a string 
longer than 16,390 characters this issue can be easily 
reproduced. 
 
private static String MY_DATA; 
 
PreparedStatement.setCharacterStream(2, new 
StringReader(MY_DATA));

See ERROR DESCRIPTION.

Use PreparedStatement.setCharacterStream(int, Read, length) or 
PreparedStatement.getCharacterStream(int, Read, length) which 
specifies the length of the data.
