Java 7 was released yesterday and some guys from the Apache Lucene & Apache Solr community quickly came up with a couple of issues which lead them to … When using compressed oops in a 64-bit Java Virtual Machine process, the JVM software asks the operating system to reserve memory for the Java heap starting at virtual address zero. If the operating system supports such a request and can reserve memory for the Java heap at virtual address zero, then zero-based compressed oops are used. Don’t set Xmx to above the cutoff that the JVM uses for compressed object pointers (compressed oops); the exact cutoff varies but is near 32 GB. Tested with dev-java/icedtea-bin-3.2.0. Compressed oops represent managed pointers (in many but not all places in the Java Virtual Machine (JVM) software) as 32-bit object offsets from the 64-bit Java heap base address. With compressed oops enabled, object references are represented as 32-bit offsets instead of 64-bit pointers, which typically increases performance when running the application with Java heap sizes smaller than the compressed oops pointer range. Java comes with “java.util.zip” library to perform data compression in … The way to do this might be to store the data off the Java heap. You can do this by getting hold of some o...
