[PATCH] 8246633: Improve the performance of ObjectInputStream.resolveClass(ObjectStreamClass)

[Peter Kessler (Open Source)]

Alan,

Indeed!  Thanks for the instruction.  Running

  $ make test-image

and adding

  -nativepath:build/linux-$(arch)-server-release/images/test/jdk/jtreg/native

to my jtreg command line allows me to pass all tests that had errors, on
aarch64 and x86_64, with and without the proposed patch.

    These are tests that use native libraries and need jtreg run with 
    -nativepath with the path to these libraries. The "test" make target 
    might be want you want, to avoid your jtreg command getting too complicated.
