Hi -
I merged the code from the bloomberg master-solr-8776 branch to branch_6_6
on Solr.
When I tried to compile the solr source code, I am getting multiple
compilation errors (Attached), which seems to be due to the fact that the
branch master-solr-8776 may not be compatible with branch_6_6.
Could you please provide your input if master-solr-8776 is compatible with
branch_6_6?
If this is not the case then how to proceed with using fix in
master-solr-8776 with branch_6_6 can a new patch be created for this?
Thank you,
Roopa
