/home/horst/dev/NB/MVA-DB/EvtEditor/nbproject/build-impl.xml:604: The following error occurred while executing this line:
/home/horst/dev/NB/MVA-DB/EvtEditor/nbproject/build-impl.xml:246: Compile failed; see the compiler error output for details.
BUILD FAILED (total time: 0 seconds)


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Replacing
Object cvA = cv instanceof Integer ? new int[1] : cv instanceof Number ? new double[1] : new String[1];
by
Object cvA = Array.newInstance( cv instanceof Integer ? int.class : cv instanceof Number ? double.class : String.class, 1);
works, aka that seams to be duplicate of bug  id 6500343

Unclear why netbeans compileOnSave (incremental)  doesnt fail but "clean and build" creates the fault observed
