I had POI 3.17 before in my project and as the black duck scan resutl was shwoing vulnerability I had to switch to 4.0 or better. After I downloaded the 4.1.2 jar ( THIS IS A ANT PROJECT). I am having build issues which says this :
Compiling 500 source files to C:\Users\k\project\ts\ts\build\WEB-INF\classes C:\Users\k\project\ts\ts\tool\src\com\vh\tool\services\DNBBatchThread.java:197: error: cannot find symbol [javac]
if (cell.getCellType() == HSSFCell.CELL_TYPE_NUMERIC)
