[9] RFR(S): 8153514: Whitebox API should allow compilation of <clinit>

[Tobias Hartmann]

Hi,

please review the following patch that adds support to the Whitebox API to compile the static initializer of a class:

https://bugs.openjdk.java.net/browse/JDK-8153514
http://cr.openjdk.java.net/~thartmann/8153514/webrev.root.00/
http://cr.openjdk.java.net/~thartmann/8153514/webrev.00/

The static initializer is not accessible through reflection and can therefore not be compiled by using the existing WhiteBox::enqueueMethodForCompilation feature.

I did not add tests for the new feature because that would require implementing additional methods to check for a successful <clinit> compilation (or parsing the log compilation output). The feature will be exercised by JDK-8153515 which should be enough for testing.

Thanks,
Tobias
