jcstress 0.1.2

[Aleksey Shipilev]

Hi,

jcstress 0.1.2 is available at Maven Central. It includes the fix for single,
but nasty bug:

 *) When walking the classes at runtime to check if @Contended is working, we
have inadvertently initialized all the classes. Oops. Fixed:
    https://bugs.openjdk.java.net/browse/CODETOOLS-7901899

Thanks,
