A DESCRIPTION OF THE PROBLEM :
JTables are always reported as empty by VoiceOver on OS X.
For example, when focusing a table with VoiceOver enabled, VoiceOver says "<accessible table name>, empty , table has keyboard focus", even if the table is not empty. When navigating through the table, none of the table contents is ever read.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the below example on OS X. Enable Voiceover (Cmd-F5).

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The table should be reported as containing some rows and columns. When navigating the table the contents of cells, rows, or columns (as appropriate) should be read.
ACTUAL -
In the below example, VoiceOver reads:
"Java, AccessibilityTest, Window, accessible table, empty , table has keyboard focus."
Click or use the keyboard to navigate the table. VoiceOver says nothing.

REPRODUCIBILITY :
This bug can be reproduced always.
