request for backport - 6755847 and 6864028

[Dmitry Cherepanov]

Hello,

This is a request for backport 6755847 and 6864028 to JDK6

6755847: (launcher) will trigger assertions in debug build
http://hg.openjdk.java.net/jdk7/jdk7/jdk/rev/e7f373751c6b

6864028: Update the java launcher to use the new entry point JVM_FindClassFromBootLoader
http://hg.openjdk.java.net/jdk7/jdk7/jdk/rev/3323e6c925f9

There is a mismatch between FindClassFromBootLoader_t in JDK (with 3 params) and JVM_FindClassFromBootLoader in Hotspot (with 2 params) and backport resolves this. Patches apply cleanly.

Thanks

Dmitry
