How current does the build jdk have to be for cross builds

[Thomas Stüfe]

Hi,

quick question, I'm doing arm crossbuilds, trying to find an errornous
patch with bisecting. With crossbuild, I am specifying build-jdk.

How current does the build-jdk have to be? If the build jdk does not fit
the source I am trying to build, would that be immediately obvious or would
I get strange errors? I am gauging whether to rebuild the build jdk for
every bisect point.

Thanks, Thomas
