[wildfly-dev] app policy race

[Stuart Douglas]

I think what is happening is two security domains are being started at the
same time, which results in two concurrent put() calls.

Sometimes this will result in both items being put into the same place in
the table, and one put() will essentially be lost.

Using a sync map makes this problem go away.
