Max Heap , real free memory and GC invoke Posted: Dec 2, 2002 1:55 AM

Hi,

My question is about Garbage Collector invoking. Ash far as I know Garbage collector implicitly is invoked when it reaches maximum heap size assigned to the JVM. Lets say if I have
java -Xmx25m Blabla

So when JVM memory usage will reach 25M it will not be able to create more objects and will run GC tu free not strongly reffered objects. My question what if on my system is only 20 Mb available free memory (lets say 10Mb RAM and 10MB virtual). Will GC be executed when it reaches phycical memory limit or it will try to reach 25 Mb and throw OutOfMemoryError ?

Thank You very much

Tony
