Weldon, I added 'alloc' support to JIRA 816 (magic2.zip file) Now it supports objects allocation only, not arrays. MMTk allocation works only for class named 'test' and methods with prefix 'testAlloc'. To turn it on use "-Xjit jet::alloc4j" option.
I had a problem with implementation: usual 'new' vm helper does vtable field initialization in allocated object space by itself. Your alloc() method doesn't. In the patch in JIRA I added vtable initialization code right after the alloc() call to JIT, that is actually bad design decision (IMO). Can we replace the 'alloc()' call with another Java method that uses unboxed API and behaves exactly like 'new' helper? +The test in the patch throws NullPointerException because no memory is allocated in alloc() now and JET tries to write vtable data by NULL address.
