Oh, that is interesting. Thank you for correcting me. I guess they  
needed a RuntimeException and picked OOME. Grepping through the  
sources reveals that there are some other sources of OOME's too. I'd  
have to look at them to see which resource is actually being depleted,  
but it's a reminder to read the exception message with some attention.
