Description Sven Gothel 2014-02-12 02:09:17 CET 
Class.forName(..) may cause a dramatic performance hit in special cases,
i.e. long CLASSPATH or multiple daisy-chained ClassLoader.

Try to cache ClassLoader lookup results or avoid lookup alltogether.

  Instrument ReflectionUtil's forName(..) usage

c5964bf2e3ebd6e05a7d551b033355c21ca9eea9
    GLProfile, GLContextImpl:
      - ReflectionUtil.DEBUG_STATS_FORNAME: Dump forName stats if set
      - Cache GL*Impl and GL*ProcAddressTable Constructor<?> for GLContextImpl's createInstance(..)
      - Remove off-thread early classloading thread which only adds complications
    
    DisplayImpl:
      - Remove one redundant availability test
