           Summary: JamVM + jtreg  LocalOnlyTest sends SIGQUIT to all

jamvm_jmm_GetLongAttribute_201_PID.patch

Problem:
When JamVM are used to run check-jdk then a SIGQUIT are sent to all processes
when the openjdk/jdk/test/sun/management/jmxremote/bootstrap/LocalOnlyTest.java
test exit.

Output from the test are:
jmm_GetLongAttribute: Unknown attribute 201
name = -1 at hp
vmid = -1

The problematic part of the test code are:
        VirtualMachine vm = VirtualMachine.attach(vmid);

Here vmid are set to "-1" instead of the JVM PID while performing the test
using JamVM.

The attached patch fixes this bug by patching JamVM to implement the
jmm_GetLongAttribute: Unknown attribute 201 and return its PID when requested.
