important regression with buffered NIO commit #5708: intermittent
java.nio.BufferUnderflowException serving Rails some requests
-------------------------------------------------------------------------------------------------------------------------------
Key: JRUBY-2032
URL: http://jira.codehaus.org/browse/JRUBY-2032
Project: JRuby
Issue Type: Bug
Components: Interpreter
Environment: JRuby head after rev #5708, Java6, Ubuntu Linux Kernel
2.6.14
Reporter: Raphael Valyi
Priority: Blocker
Hi, SVN commit #5708 just induced an intermittent regression: the same
page can be served or break into the following stack. It doesn't seem to occur
on any page but rather on page we server after a Rails redirect_to. This is a
blocker bug for 1.1 I think. Was working like a charm before rev #5708, sure
about that.
Hope this helps,
Raphaël Valyi.
