Andrew Cornwall updated HARMONY-5489:
-------------------------------------

    Summary: [pack200][classlib] java.util.ZipException("No Entries") on unpack close()  (was: [pack200][classlib] ClassBands.getCodeHandlerClassRCN() sometimes contains nulls?)

Using Archive.unpack(), the same test case throws:

Thread [main] (Suspended (exception ZipException))	
	JarOutputStream(ZipOutputStream).finish() line: 159	
	JarOutputStream(ZipOutputStream).close() line: 59	
	Archive.unpack() line: 153	
	TestUnpack.main(String[]) line: 15

> The ClassBands.getCodeHandlerClassRCN() method answers an array of arrays of Strings (which is stored as handlerClassTypes in BcBands.unpack). That structure sometimes contains what appear to be inappropriate nulls, which leads to the following code failing:
> (from BcBands.unpack()):
>                     if(handlerCount != null) {
>                         for (int j = 0; j < handlerCount[i]; j++) {
>                             String handlerClass = handlerClassTypes[i][j];
>                             CPClass cpHandlerClass = new CPClass(handlerClass);
>                             ExceptionTableEntry entry = new ExceptionTableEntry(
>                                     handlerStartPCs[i][j], handlerEndPCs[i][j],
>                                     handlerCatchPCs[i][j], cpHandlerClass);
>                             exceptionTable.add(entry);
>                         }
> handlerClassTypes[i][j] can be null, which means that handlerClass is null. The code then fails when trying to create a new CPClass(null).
