Hi,

We want to port thread migration/movement code, which as of date is in =
JDK
1.1.5 to JDK 1.2.2.

Following JDK functions from JDK source code are not accessible from =
Java
native code because their Scope/binding is done locally in JDK 1.2.2 =
shared
library libjvm.so where as it was done globally in JDK 1.1.5 shared =
library
libjava.so

Can someone help me? Has any body done any work in this area?

InitializeExecEnv
ExecuteJava
CreateNewJavaStack
PcinCompiledCode
ProcStackSize
ProcedureFindThrowTag
_binclass_lock
get_binclasses
get_nbinclasses
isHandle
threadCreate
hpi_thread_interface
sysThreadInit
sysThreadExit

Also

sysThreadInit() and sysThreadExit()  which are part of the jdk1.1.8 are =
not
available in jdk1.2.2.

Can you help out in getting the same functionality for above functions =
from
jdk1.2.2.

java_monitor ( variable declared as an 'int' ) is not being used in
jdk1.2.2.

Could you please tell the exact functionality of this.


Regards
Dayanand
