Another potential source of these “Java heap space” OOMs arises with the use offinalizers. If a class has afinalizemethod, then objects of that type do not have their space reclaimed at garbage collection time. Instead, after garbage collection, the objects are queued for finalization, which...
In this example, anIntegerarray with a very large size is attempted to be initialized. Because the Java heap is insufficient to allocate this array, it throws ajava.lang.OutOfMemoryError: Java heap space Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at OutOfMemoryE...

The One Billion Row Challenge (1BRC) is a fun exploration of how far modern Java can be pushed for aggregating one billion rows from a text file. Grab all your (virtual) threads, reach out to SIMD, optimize your GC, or pull any other trick, and create the fastest implementation for so...
it's difficult to predict when the garbage collector cleans up permgen space. Pressing the button in Run GC in jconsole does not do the trick. Only when you encounter a java.lang.OutOfMemoryError: PermGen space exception can you be sure that there really was no memory. This is a bit mo...
java.lang.OutOfMemoryError: request <size> bytes for <reason>. Out of swap space? Although it appears that an OutOfMemoryError is thrown this apparent exception is reported by the HotSpot VM code when an allocation from the native heap failed and the native heap may be close to exhaustion...
