JDK solaris-sparcv9 bundle provides both 32-bit and 64-bit VM
(32-bit VM is launched by default), both VM are running well in b49:

  $ .../jdk1.5.0-b49/solaris-sparcv9/bin/java -d64 -version
  java version "1.5.0-beta2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b49)
  Java HotSpot(TM) 64-Bit Server VM (build 1.5.0-beta2-b49, mixed mode)
 
  $ .../jdk1.5.0-b49/solaris-sparcv9/bin/java -version
  java version "1.5.0-beta2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b49)
  Java HotSpot(TM) Client VM (build 1.5.0-beta2-b49, mixed mode)

JDWP agent runs fine with 64-bit VM, but dumps core running
with 32-bit VM:

  $ .../jdk1.5.0-b49/solaris-sparcv9/bin/java -d64 -agentlib:jdwp=transport=dt_socket,server=y,suspend=n -version
  Listening for transport dt_socket at address: 65236
  java version "1.5.0-beta2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b49)
  Java HotSpot(TM) 64-Bit Server VM (build 1.5.0-beta2-b49, mixed mode)

  $ .../jdk1.5.0-b49/solaris-sparcv9/bin/java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n -version
  #

  # Problematic frame:

  [error occurred during error reporting, step 60, id 0xb]

  #

  #

This crash is reproduced for any JDWP agent mode (i.e, server=y|n,suspend=y|n).

Running JDWP agent with 32-bit VM from solaris-sparc bundle
shows no crash:

  $ .../jdk1.5.0-b49/solaris-sparc/bin/java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n -version
  Listening for transport dt_socket at address: 65243
  java version "1.5.0-beta2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b49)
  Java HotSpot(TM) Client VM (build 1.5.0-beta2-b49, mixed mode)

With the previous JDK build b48 this crash also does not occur,
though error messages are printed in some modes of JDWP agent:

  $ .../jdk1.5.0-b48/solaris-sparcv9/bin/java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y -version
  Listening for transport dt_socket at address: 65248
  <^C does not kill this>

  $ .../jdk1.5.0-b48/solaris-sparcv9/bin/java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n -version
  Listening for transport dt_socket at address: 65244
  java version "1.5.0-beta2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b48)
  Java HotSpot(TM) Client VM (build 1.5.0-beta2-b48, mixed mode)
  JDWP exit error JVMTI_ERROR_INVALID_MONITOR(50): on raw monitor enter
  FATAL ERROR in native method:
  JDWP on raw monitor enter, jvmtiError=JVMTI_ERROR_INVALID_MONITOR(50)

Generated hs_err_pid1580.log includes empty stack trace,
but dbx shows that crash occurs in Agent_OnLoad (see Comments).

This bug affects the following JDI tests of testbase_vm:

  nsk/jdi/VirtualMachineManager/createVirtualMachine/createVM002
  nsk/jdi/VirtualMachineManager/createVirtualMachine/createVM003
  nsk/jdi/VirtualMachineManager/createVirtualMachine/createVM004
  nsk/jdi/VirtualMachineManager/createVirtualMachine/createVM005

These tests ignore Java options and launch debuggee VM in default
32-bit mode on solaris-sparcv9 platformm, that leads to crash.
There is RFE for these tests to not to ignore Java options:

  4943437 TEST_RFE: createVM002 does not honor DEBUGEE_VM_* setting

The same crash occur just running JDB from solaris-sparcv9 bundle
with any application, e.g., HelloWorld.java:

$ .../solaris-sparcv9/bin/jdb HelloWorld
Initializing jdb ...
> run
run HelloLoop
VM start exception: VM initialization failed for: .../solaris-sparcv9/jre/bin/java -Xdebug
