I tried with the Fedora 14 rpm and with HEAD:

F14 rpm:
$ java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.7) (fedora-52.1.9.7.fc14-x86_64)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)

$ java -Djava.system.class.loader=PrintfClassLoader -version
Initializing Printf classloader....
I am the Printf classloader!java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.7) (fedora-52.1.9.7.fc14-x86_64)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)


With HEAD:
$ ./builds/icedtea6/openjdk.build/j2sdk-image/bin/java -version
java version "1.6.0_22" OpenJDK Runtime Environment (IcedTea6 1.11pre+r95b6b42f92c3) (Fedora build 1.6.0_22-b22)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

$ ./builds/icedtea6/openjdk.build/j2sdk-image/bin/java -Djava.system.class.loader=PrintfClassLoader -version
Initializing Printf classloader....
I am the Printf classloader!java version "1.6.0_22" OpenJDK Runtime Environment (IcedTea6 1.11pre+r95b6b42f92c3) (Fedora build 1.6.0_22-b22)
