Problem using -Xbootclasspath/p

[Lindenmaier, Goetz]

Hi Roman,

I just had the same problem.
I fixed it by

1.)    Copying a rt.jar from our Java 7 VM into the jvm2008 directory

2.)    Patching the file Compiler.java, see below, and rebuilding SPECjvm2008.jar

3.)    Adding -Xbootclasspath/p:lib/javac.jar to the command line

I guess one can not submit results with this inofficial jar, but for internal use it's fine.

Best regards,
  Goetz.
