hello,

Recently we encounter this bug:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4949631

now we are looking the work arround/fix,
from the link it said the released fix is " mustang(b14)",
is it mean that 1.4.2_14 fixed the problem ?
anyone know how to find the fix list of 1.4.2_14 ?

Thanks
Lester

No. It means that mustang (Java 6) beta 14 fixes the problem.
It is not fixed in 1.4.2

thx~~!

We are using Weblogic + Sybase and enconter this error when uploading a pdf file to sybase, so i think change encoding is not a option.

The evil thing is , it not just fail the upload action, but hang the connection, block the table and cannot release until we kill the query process in db ...

Most info. on Lester's problem:
*********************************
Filename WITH BufferOverFlowException
071006CLAIMS-1.pdf

The most evil thing happened with different filenames.
We tried to change the filename a bit. There will NOT have BufferOverflowException.
Filename WITHOUT BufferOverFlowException
071006CLAIMS-1..pdf or 071006CLAIMS-1.evil.pdf

These are programming steps caused the exception
1) read the whole file as a byte[] (8.56MB).
2) pass the byte[] to a EJB (CMT) in weblogic.
3) weblogic try to save the byte[] to Sybase.
(jConnect (TM) for JDBC(TM)/5.5(Build 25329)/P/EBF11937/JDK13/Fri Apr 30 2:16:56 2004).
4) throw java.nio.BufferOverflowException for this particular file only.

The problem caused:
Even though the Exception was catched, the transaction fallback, but the sybase DB still block this process.
The connection never relased unless you kill it.

Could any expert give us some comments?
Java bug? Weblogic bug? Sybase JDBC bug? Sybase DB bug?

Why there was BufferOverflowException?

The is the Exception thrown from java nio lib..
