Anurag Shekhar updated DERBY-2586:
----------------------------------

    Attachment: derby-2586.diff

Modified UTF8Reader to wrap input stream (received via constructor) in BufferedInputStream

I haven't run the complete suite but org.apache.derbyTesting.functionTests.tests.jdbcapi._Suite
runs with out any failure (in 1,111.169 sec)

org.apache.derbyTesting.functionTests.tests.jdbcapi.BlobClob4BlobTest  now takes 151.561 sec.

> Dan reports that BlobClob4BlobTest.tesPositionAgressive takes very long to run:
> > In a test run (junit-all) of 5,816 fixtures that took 4124 seconds (~68mins) *three*
fixtures took 53% of the total time.

> > testNetworkServerSecurityMechanism    497.280 seconds
> > testTypesInActionStatement            128.928 seconds 
> Knut Anders reports that this behavior is fairly new:
> > It seems like it started taking a lot more time at revision 530085. I had
> > run the tests at an earlier revision.
> This was a check-in for DERBY-2346.  Since Anurag is currently on vacation, I will try
to look into this.
