JTreg upwards compatibility?

[Volker Simonis]

Hi,

I wanted to ask if JTreg is supposed to be upwards compatible.

I.e. should it be possible to run OpenJDK 7 and 8 regression tests
with the newest JTreg version?

If not, is there a source which describes the required JTreg version
for successfully running the regression tests of the various OpenJDK
releases? Which JTreg versions is Oracle using for running its OpenJDK
7 and 8 regression tests?

Thank you and best regards,
Volker
