Does the JVM ever re-compiles compiled code?

[Ion Ionascu]

Hi,


I hope this is the right mailing list to ask this question.

Could you please tell me if the JVM ever re-compiles already compiled
bytecode? And, is the compiled code ever brought back to a state where it
is just interpreted?

I am curious about re-compilation because the server compiler is set by
default to compile code after 10000 accesses in order to statistically
guarantee that enough information has been gathered to do the best
optimisations. But, does the JVM continue to track code usage after it is
compiled?


Thank you,
Ion Ionascu
