This is fixed in 3.8 via bug 351498. Please try one of the recent 3.8 builds.

Are you sure bug 351498 is the same?
Its stack trace is totally different and its target milestone is 3.7.1. However, I'm actually seeing my exception in 3.7.1.

Satyam, looks like this one is yet to be released in 3.7.x, doesn't it?

Bug 351498 was released into the BETA_JAVA7 branch, which then
become 3.7.1, right?

Sorry, I didn't notice that.
Yes, it should have been fixed in 3.7.1.

The problem is different. Hence, reopening.
