Hi All,
Another issue we discovered with WO 5.4.3:
This code:
NSArray array = new NSArray(new Object[] {"86309", "", "6.4000",
"6.4000"});
System.out.println(array.toString());
Outputs the following:
5.3.3 :
( "86309", "", "6.4000", "6.4000" )
5.4.4 :
( 86309,
,
6.4000,
6.4000 )
We relied on NSArray toString() method to generate the plist format
for an NSArray.
That was a mistake. That is the job of NSPropertyListSerialization.

With WO 5.4.3 the output is different and then when we try to parse
the string generated by WO 5.4.3 back into an NSArray using
NSPropertyListSerialization.propertyListFromString we get this
exception:
java.lang.IllegalArgumentException: Property list parsing failed
while attempting to read unquoted string. No allowable characters
were found. At line number: 1, column: 9.

The workaround is to write our own code for outputting NSArray. But
this seems like a WO 5.4.3 bug to me.
