> We now have one more week to prepare our build for Java 9 Jigsaw. The next Java 9 EA build will now contain the new Java 9 module system. From that time on, it is no longer possible to test Java 9 unless we fix remaining bugs. Currently Solr does not pass at all, because almost every test fails because the RAMUsageEstimator tries to look into objects in static field where the internals were hidden by Java 9:

> I have 2 suggestions:
> - for now disable the static heap usage checks for Java 9 (how? See below!)
> - fix the problems! Mainly we have to ensure that *all* static, non-final fields in tests pointing to Java obects are nulled on tear down (@AfterClass).
> I have no idea how to do the disabling conditionally. Maybe Dawid Weiss can give a hint.
> In addition, almost every Hadoop test fails with Java 9 module system! Unless Hadoop fixes this and we have updated libs, our only chance is to disable all hadoop related stuff with Java 9 preview builds - sorry. I'd like to add a new Test annotation {{@DisableWithJava9Jigsaw}}, which disables the test if running under Java 9 Jigsaw.
