Jigsaw test failures

[Sean Mullan]

There are a few jigsaw regression test failures:

     * org/openjdk/jigsaw/cli/ModuleFormatTest01.sh
     * org/openjdk/jigsaw/cli/jmod-signed.sh
     * org/openjdk/jigsaw/cli/signed-module.sh

The last one is due to the cacerts file being empty. We have a fix coming for that.

However, the previous two appear to be the same failure and is caused when it 
compares the bytes of one of the classes in an installed module with the bytes 
in the module file (I think). This is the stack trace from the 
ModuleFileFormatTest01.sh test:

java.lang.RuntimeException: file compare failed 1

	at ModuleFormatTest01.compare(ModuleFormatTest01.java:407)

	at ModuleFormatTest01.run(ModuleFormatTest01.java:62)
	at ModuleFormatTest01.main(ModuleFormatTest01.java:49)

Has anyone looked at this more closely?

Thanks,
