RFR (S) 8001108: an attempt to use "<init>" as a method name should elicit NoSuchMethodException

[John Rose]

Please review this change for a change to the JSR 292 implementation:

http://cr.openjdk.java.net/~jrose/8001108/webrev.00

Summary: add an explicit check for leading "<", upgrade the unit tests

The change is mostly to javadoc and unit tests, documenting and testing some corner cases of JSR 292 APIs.

In the RI, there is an explicit error check.

Thanks,
— John

P.S. Since this is a change which oriented toward JSR 292 functionality, the review request is to mlvm-dev and core-libs-dev.
Changes which are oriented toward performance will go to mlvm-dev and hotspot-compiler-dev.
