RFR 8168069 : X509TrustManagerImpl causes ClassLoader leaks with unparseable extensions

[Xuelei Fan]

Hi,

Could I get the following update reviewed?
    http://cr.openjdk.java.net/~xuelei/8168069/webrev.00/

In the lazy initialization holder in SSLContextImpl, an exception is 
reserved as static in order to check if the holder is initialized 
properly.  If the exception had a strong referent to some object, the 
object will be out of the cycle of garbage collection.

With this update, the original exception is debug logged, and a new 
exception with the same exception message as the original one.

Code cleanup, no new regression test.

Thanks & Regards,
Xuelei
