RFR: 8146986: JDI: Signature lookups for unprepared classes can take a long time

[serguei.spitsyn at oracle.com]

Hi Egor,

The fix looks good to me.

Thank you for taking care about it!
I've targeted this enhancement to 13.

How do you test it?
It would be safe to run all JDI tests to make sure no new timeouts are 
observed.

Thanks,
Serguei
