JDK-8163486 - NumberAxis: inaccurate rendering of ticks when tick unit is low
Description
1. Run Ensemble8 and open the AreaChart demo.

For the xAxis:

2. Uncheck the autoRanging checkbox.
3. Set lowerBound to -2
4. Set upperBound to 10
5. Set tickCount to 0.5
6. Now set the minorTickCount to 10

Observe that the minor ticks are no longer rendered. They only appear back when you set the minorTickCount to the value of 7 or less.
I realize that there might be not enough pixels to render all 10 minor ticks in the space available, however, they shouldn't disappear altogether.

@Steve: Was this reassigned back to me on purpose? Martin has been taking care of charts issues for quite a while now so he is the best person for the job, unless I'm missing some context?

Actually, the exact size of my Ensemble window on Mac is 1024x681

Note that this may depend on the size of the Ensemble window. For me it is sized at about 1024x700 or so. The chart is displayed on the right, and the DESCRIPTION, VIEW SOURCE, etc. are displayed on the left.
