I'm looking into the issue.
Could you please share the class/method that causes assertion ?

All,
Implementations of the abstract classes from:
http://cs.anu.edu.au/~Steve.Blackburn/private/mmtk-20060714.jar :::
src/org/mmtk/vm/*.java have been created.
They are svn commited at:
drlvm/trunk/vm/MMTk/ext/vm/HarmonyDRLVM/org/apache/HarmonyDRLVM/mm/mmtk/*.java
The ant build.xml has been modified to build the new "ext" directory
as well as a modified "test.java"
You should be able to download the mmtk-20060714.jar from above. Then
overlay the newly committed svn files. Then type "ant" to create the
MMTk and test class files.
To run the test class, first build jitrino.jet with the write barrier
mods, then type:
.......\drlvm\trunk\build\win_ia32_msvc_debug\deploy\jre\bin\ij.exe -Xb
ootclasspath/p:.;mmtk.jar -Xem jet: -Xjit jet::wb4j %1 test
You should see:
org.apache.HarmonyDRLVM.mm.mmtk.ObjectModel
org.apache.HarmonyDRLVM.mm.mmtk.ReferenceGlue.getReferencesAreObjects()
was called
org.apache.HarmonyDRLVM.mm.mmtk.Memory.getAvailableStartConstant(),
needs fixing now
org.apache.HarmonyDRLVM.mm.mmtk.Memory.getAvailableEndConstant(),
needs fixing now
top of test wjw------
test0 - ok
test1 - ok
test2 - ok
testWB - seems ok
The above "...was called" and "...needs fixing" are stubbed out MMTk
methods that are invoked when, "VM vm_init = new VM();" in test.java
is executed. My next step is to work on the stubs so that NoGC will
run properly.
I also recently discovered what could be problem with jitrino.JET
compiling OPCODE_LCMP. Jitrino.JET is core dumping. This problem
occurs when attempting to compile a method that uses vmmagic
functions. More details shortly. Below is a stack trace of where the
JIT runs into problems:
