want SA to ignore the version, you need to provide
the
"-Dsun.jvm.hotspot.runtime.VM.disableVersionCheck"
option to the java launcher from the command
line. This is the case even if you are not using
the debug server. However since 'jstack' and
similar tools don't take the "-D" option of java,
you can invoke it as follows:<o:p></o:p></p>

attach to another jvm version possible?<br>
<br>
Hi all,<br>
<br>
documentation for SA Debug Server Attaching
Connector here:<br>
<a
href="https://docs.oracle.com/javase/8/docs/technotes/guides/jpda/conninv.ht"
target="_blank" \
moz-do-not-send="true">https://docs.oracle.com/javase/8/docs/technotes/guides/jpda/conninv.ht</a><br>
ml#Connectors states that the SADebugServer has
to run on the same vm<br>
version as the debugee process, but "the
debugger does not have to be the same bit size
and version."<br>
However any attempts to connect from another
version fail with
sun.jvm.hotspot.runtime.VMVersionMismatchException.<br>
<br>
Please help, what do I do wrong (locally for
simplicity):<br>
- start the debugee process with jdk1.8.0_162 -
get the PID<br>
- start "jdk1.8.0_162\bin>jsadebugd.exe PID"
- all starts well<br>
- trying to attach jstack, jdb or whatever from
another version:<br>
jdk1.8.0_152\bin>jstack localhost<br>
Attaching to remote server localhost, please
wait...<br>
Error attaching to remote server:<br>
sun.jvm.hotspot.runtime.VMVersionMismatchException: Supported versions<br>
are 25.152-b16. Target VM is 25.162-b12<br>
sun.jvm.hotspot.debugger.DebuggerException:<br>
