Hi!

I've discovered a problem in CDO Clob handling:

here is the code, which is located in org.eclipse.emf.cdo.spi.server.StoreAccessor:

writeClob(id, -size, new InputStreamReader(new LimitedInputStream(in, -size)));


Next, in org.eclipse.emf.cdo.server.internal.db.DBStoreAccessor.writeClob(byte[], long, Reader)

stmt.setCharacterStream(3, reader, (int)size);


Code in StoreAccessor implies, that the amount of chars (passed to setCharactedStream) is equal to number of bytes passed to LimitedInputStream.

That leads to commit exceptions, whenever text in non-ascii encoding is submited.
Also, i've noticed that there is no encoding passed to InputStreamReader constructor, which means that encoding is platform-dependant, which can easily lead to more issues in future.

Hi Leonid,

Could you raise a bugzilla with a Gerrit patch-set containing a JUnit
test to reproduce your issues.

Best Regards.
