[infinispan-issues] [JBoss JIRA] (ISPN-9778) XidImpl implementations can optimize some byte[] allocations

XidImpl implementations can optimize some byte[] allocations ------------------------------------------------------------ Key: ISPN-9778 URL: https://issues.jboss.org/browse/ISPN-9778 Project: Infinispan Issue Type: Bug Components: Transactions Reporter: William Burns Priority: Major Fix For: 10.0.0.Beta1 The EmbeddedXid and XidImpl classes show up on profiler for allocating byte[] in a local environment. 1. We should be able to remove the branch byte[] completely as well as its accompanying AtomicInteger and just return an empty byte[] that is cached (ie. Util.EMPTY_BYTE_ARRAY). 2. We can use the byte[] that is provided from the create method directly in XidImpl, which would reduce our allocation to just the 1 byte\[24\] for embedded or byte\[32\] for remote. -3. We can return the byte[] directly for getGlobalTransactionId without copying.-
