RFR: 8149743: JVM crash after debugger hotswap with lambdas

[Coleen Phillimore]

This fix looks good.   The test looks like it uses some framework I 
don't know, in a directory that I don't usually run tests in.

We have some redefinition tests in hotspot/test/runtime/RedefineTests - 
can you write one with source code there instead?

I linked an old bug to this, can you see if they are the same?

Thanks,
Coleen
