Always, absolutely always, first check for NULL values before comparing against empty string, except if your source data will never deliver NULL values; everything else can lead to memory leaks which is why you receive Null pointer exceptions. Please change your code accordingly. Regards, Nico

Thrown when an application attempts to use null in a case where an object is required. These include: Calling the instance method of a null object. Accessing or modifying the field of a null object. Taking the length of null as if it were an array. Accessing or modifying the slots of null as if it were an array.

A null pointer is one that points to nowhere. When you dereference a pointer p, you say "give me the data at the location stored in "p". When p is a null pointer, the location stored in p is nowhere, you're saying "give me the data at the location 'nowhere'". Obviously, it can't do this, so it throws a null pointer exception. memory leaks - What is a StackOverflowError? - Stack Overflow What is a StackOverflowError, what causes it, and how should I deal with them? memory-leaks exception-handling out-of-memory stack-overflow share | improve this question 05.03 NullPointerException – Java-Blog-Buch Eine NullPointerException wird immer dann geworfen, wenn null anstelle einer Instanz eines Objekts verwendet wurde.

With this utility you can simply find memory leaks (CRT and COM) in your program (with almost no time-cost during runtime). Each leak is written to a file with the callstack of the allocation.

The next generation Java Plug-in combines the best architectural features of applet and Java Web Start technologies. It provides a robust platform for deployment of Java and JavaFX content in the web browser. If value types are conceived as a memory layout mechanism only, then their primary usage will be via a Java pointer. The flattened realization in registers (in method types) will be a fiction to be uneasily maintained, at the cost of…
