The version of JAXB used by that area of the code is the version of JAXB
included in the JDK that you are using for the build. So the question is
what version of the JDK are you using?
Hi Juan,
I am using icedtea7 to build openjdk-7. And I found the JAXB file.
note: I saw same line using java-1.8.0-openjdk installed from repo.
Would you like to give some advice how to debug this issue? Does jdb could
debug such code?
Thanks a lot.
