8015739: Background of JInternalFrame is located out of JInternalFrame

[GoeLin]

I backport this because it fixes an obvious problem.
The backport is based on the commit to 17.
The test reproduces the issue and passes with the fix.

I had to resolve due to context.
I adapted the test to work with Java 11.
