Hi All,
I meet something interesting when I try to improve/fix a bug on
javax.sql.rowset.serial.SerialJavaObject, the Spec reads:
(The constructor)
"public SerialJavaObject(Object obj)

Throws:

Jimmy, it's possible to insert free() automatically in jitted code to
reclaim some short-lived objects. This can be a supplementary to the
GC, and probably improve the overall performance. Tingpeng had
previous discussions with me on this topic actually.
Sorry I don't know the context.

Hi,
I've noticed that APIs of javax.sql.rowset and
javax.sql.rowset.serial are still missing. Currently, the results of
API comparison[1] show that javax.sql.rowset is missing one class, and
javax.sql.rowset.serial has 22 bad methods, missing 59 methods and 6
constructors. And I guess there'

In this case, I guess the rarely used port may be suitable, though it
is not perfect and may cause failure (in very little possibility?) Or
let's make the test as a special test, as exclude test, or manual
test?
I suggest we should never use Support_PortManager any more.

Hi All,
I happen to meet a package private method of DatagramSocket(and
its child class MulticastSocket), named isMulticastSocket. I search in
the luni package but find no line refers to this method. And a simple
search in native code shows no native code refers to this method by
reflection.
o select the JRE to use from the GUI so that you can run
directly from the workbench. The launch configurations have been undergoing
some updates recently and I don't see the dialog at the moment.

Native reflection caching is to cache reflection method/field id
