I use sql developer version 3.2.20.09
i set the developer to look in "c:\scripts" directory the scripts.
when i execute the script (F5 or F9) (@wsession.sql for example) the first time works. from the second always generates the errors:
if a restart the developer, the same problem occurs (works the first time and doesnt work from second).
if i take the sql inside the script and put it in the developer worksheet (the same place that i called @wsessoin,sql for example) and execute it (F5) it works fine.
Working with the developer to replicate this locally, I see it - he doesn't, and then we can progress to fix.
java.io.PipedInputStream.checkStateForReceive(PipedInputStream.java:### - this is happening in the 4.0 code base as well...
