The java launcher crashes in JLI_WildcardExpandClasspath when run with the (strange) command line "java -jar -XX"

$ /localhome/java/jdk-8-ea-bin-b28/bin/java -jar -XX
Segmentation fault

The crash reproduces on solaris-amd64 as well.

I can reproduce this on JDK7 b147 but not on JDK6u29 b11, so I guess this is something that was introduced in 7.
