Issue/Introduction

Resolution

It is fixed in SCG v1.2.4, however, if upgrading TAS first it failed to upgrade and it was never able to successfully update the SCG tile.


WORKAROUND

Option 1)  Upgrade SCG first.

Option 2) Revert to the older java Buildpack 4.48, then upgrade the SCG tile to 1.2.4, once upgraded put java Buildpack back to the intended version.
