Licensee has reported the following, during efforts to port their current VM to Java 6.
During our efforts to port our current XXXJVM to Java 6. During the execution of this
task, I have come across a problem connected with the UseSuperWord option. I noticed
that this option is disabled by default in the latest version, namely 4 b06.
Nevertheless, I wanted to draw your attention to the enclosed test case. The program
runs forever, thus the method initialize_int_arraycopy will occasionally get compiled.
Execution of the compiled code fails on a super word enabled VM. The erronous code
performs an incorrect value copy, which is later discovered in the method
checkandfail_int_arraycopy. However, the test case is correctly executed if the
UseSuperWord option is deactivated. See attached testcase, (arraycopytest.java)
