Problems with LambdaForms in jdk7 after u40

[Julien Ponge]

Hi,

I'm quite concerned with 7u45, too, especially as it contains a bug with method handles and fields., see:

On u40/u45, there is a huge amount of LambdaForm objects being generated (bumping us from 10k to 100k objects) which brings our application down after a while. (Update 25 does not show any LambdaForms-generation at all, at least not in -verbose:class output.)

However, in the meantime, we'd like to try getting around or current problem with jdk7u45 and so far I haven't really been able to find much detail on the changes that took place there. Is there any way we can mitigate their impact, possibly fixing our problems?
