RFR: 8261269: When using clhsdb to "inspect" a java object, clhsdb prints "Oop for..." twice

[Chris Plummer]

See CR for details. In brief, fixed the `inspect` command to remove duplicate output:

hsdb> inspect 0x00000007fef00770
instance of Oop for java/lang/Class @ 0x00000007fef00770 @ 0x00000007fef00770 (size = 160)
in: Oop for java/io/BufferedInputStream @ 0x0000000082005b08 Oop for java/io/BufferedInputStream @ 0x0000000082005b08
out: Oop for java/io/PrintStream @ 0x0000000082007b60 Oop for java/io/PrintStream @ 0x0000000082007b60
err: Oop for java/io/PrintStream @ 0x000000008200e0c8 Oop for java/io/PrintStream @ 0x000000008200e0c8 
It should be:

hsdb> inspect 0x00000007fef00770
instance of Oop for java/lang/Class @ 0x00000007fef00770 (size = 160)
in: Oop for java/io/BufferedInputStream @ 0x0000000082005b08
out: Oop for java/io/PrintStream @ 0x0000000082007b60
err: Oop for java/io/PrintStream @ 0x000000008200e0c8
