This is about referencing JavaStringTokenId class from a highlighting layer that is being used by views creation in AWT thread. The JSTI class is not yet pre-loaded and if the system is slow at the moment (possibly reading some other data from a disk) then this slowness may happen. Added code into java warmup to prevent this.

Integrated into 'main-golden', will be available in build *201206020001* on (upload may still be in progress)
