 * DESCRIPTION

 *     This test performs checking for

 *         command set: VirtualMachine

 *         command: InstanceCounts

 *     Test checks that debuggee accept the command packet and

 *     replies with correct reply packet.

 *     Test consists of two compoments:

 *         debugger: instanceCounts001

 *         debuggee: instanceCounts001a

 *     Debugger uses nsk.share support classes to launch debuggee

 *     and obtain Transport object, that represents JDWP transport channel.

 *     Also communication channel (IOPipe) is established between

 *     debugger and debuggee to exchange with execution commands.

 *     Debuggee during startup creates instances of 'nsk.jdwp.VirtualMachine.InstanceCounts.instanceCounts001.TestClass1'

 *     and 'nsk.jdwp.VirtualMachine.InstanceCounts.instanceCounts001.TestClass2' reachable via references with types

 *     which should be supported by command VirtualMachine.InstanceCounts:

 *         - strong reference

 *         - soft reference

 *         - weak reference

 *         - phantom reference

 *         - JNI global reference

 *         - JNI local reference

 *     First, debugger obtains referenceTypeID for 'nsk.jdwp.VirtualMachine.InstanceCounts.instanceCounts001.TestClass1'.

 *     Then, debugger creates command packet for InstanceCounts command with the found referenceTypeID

 *     as an argument, writes packet to the transport      channel, and waits for a reply packet.

 *     When reply packet is received, debugger parses the packet structure, extracts number of instances

 *     and checks that received value is correct.

 *     Then debugger repeat described above actions, but created command packet contains 2 referenceTypeIDs for

 *     'nsk.jdwp.VirtualMachine.InstanceCounts.instanceCounts001.TestClass1' and 'nsk.jdwp.VirtualMachine.InstanceCounts.instanceCounts001.TestClass2'.

 *         Also, test performs check for case when incorrect data is sent in command:

 *                 - create command with refTypesCount < 0, expect ILLEGAL_ARGUMENT error

 *     Finally, debugger sends debuggee signal to quit, waits for it exits

 *     and exits too with the proper exit code.

 *
