      There have been several reports of triggering various bad graph asserts in the past. The originally filed enhancement JDK-8275202 seems to fix them. But this is rather a fortunate side effect. As a result, JDK-8275202 was converted to a bug which it should not be.

      In the meantime, the fix for JDK-8319372 is a promising step towards fixing the linked duplicates of JDK-8275202 as well which supports the conversion of JDK-8275202 back to an RFE even more.

      I'm therefore filing this new bug in order to re-link all the duplicated bugs of JDK-8275202 to this one which allows us to convert JDK-8275202 back to an RFE. In the scope of this (umbrella) bug, we should do the following:
      - Check if JDK-8319372 fixes the closed duplicates of JDK-8275202.
      - If there are remaining failing cases left, we should find another solution that does not rely on the new improvements of JDK-8275202.
      - If there are no remaining failing cases left, we could still close this bug as not an issue (anymore).
