Erik,
I like your idea of trying to define the string constants
for the keys to benefit from the compiler checking and
catch any issue due to typos at compile time. My review
comments below.
Your webrev includes other cleanup. While it's good to
do the simple minor cleanup with this fix, I'd like to
the warnings cleanup changes be separated from this patch
and done by a separate CR.
* added generic types where needed.
* added suppress serialization warning where it was needed.
* removed suppress serialization annotation where it was not needed.
Specifically, I'm concerned with @SuppressWarning("serial").
Tab.java L31 - it should not be suppressed and instead be
fixed by defining the serialVersionUID (you can find the
value by running serialver tool). Same to XOperations.java and
XTable.java. I notice that the current code does suppress
"serial" warning that you should check if it should be fixed
as well.
As for the generics, ProxyClient.java and XTree.java (and
maybe some other places). When I saw the use of Iterator,
I typically would also suggest to replacethe Iterator and
while loop with foreach (L601-617 and L710, 736). Anyway,
the warning cleanup deserves a separate CR and review.
Below are comments on the change to support translateability.
sun/tools/jconsole/resources/Messages.java
I suggest to move Messages to sun.tools.jconsole since
it's a utility class and conventionally resources are put
in a "resources" subpackage (i.e. sun.tools.jconsole.resources
in this case).
The initializeMessage method uses the field name as the
key and initializes its value to its localized message via
reflection. Such approach seems strange.
Have you considered about defining the constants with
the key as the value (i.e. the variable name and its
value are the same). Instead of initializing each
static field of the Messages class, you can build
a map of a key to the localized message + itsmnemonic
key (like what you have done in building the MNEMONIC_LOOKUP
map - why not change such hash map to map from a string to
an object {message+mnemonic}). In that case, the MNEMONIC_LOOKUP
doesn't need to be a synchronized map and could be done
as the class initialization of Resources class.
It would only need to keep
Resources.getText(String) method that returns the localized
message, e.g.
Resources.getText(Messages.HELP_ABOUT_DIALOG_TITLE)
I just don't see it's worth the complexity to initialize
the static fields via reflection to get rid of a convenience
method.
It is only my suggestion and I understand that this fix needs
to be backport to 7u6. If you agree that replacing this
static field initialization logic with a separate map,
I'm okay with pushing this approach to 7u6 and push
a better fix to jdk8. Or I miss the benefit you were
considering :)
There are a few names with '_' suffix e.g. L93, 97, 104, 160
and also some names with '__' (L97, 159). Do you want to
embed the space of the message in the key name? In any case,
the key names with '_' suffix or double underscores '__' is
a little confusing. It would be better just to use '_' for
separating words of a key name and no need for '_' suffix.
The names 'CHART_COLON', 'ERROR_COLON_MBEANS...', 'JCONSOLE_COLON',
and the ones with 'COLON' to describe its message with ":"
are strange. If ":" was removed from the message in the
future, the name would need to be modified to follow this
naming convention which is overkill.
sun/tools/jconsole/Resources.java
L52-54 and also other @param, nit:generally we put
the description in the same line as the @param.
XOpenTypeViewer.java
L255: this doesn't look right - I think it should be
Comparable<CompositeData>. However, this method has
@SuppressWarning("unchecked") and why was this line
changed? Did you get other warning?
Formatting nits: it's good to go through your changes and
fix the formatting nits. The lines need to be updated to
aligned, a few examples are:
BorderedComponent.java L152
CreateMBeanDialog.java L77-78, 165-167, 169-171
MemoryTab.java L120-121, 126-127
OverviewTab.java L59-60
Plotter.java L319-321, 329-331
I didn't include all and please check the files not mentioned above.

Thanks Michael,
When it comes to ALL CAPs or SturdlyCaps, it's okay if those strings
are not translated.
Here is an updated webrev. I removed strings that were no longer in
use and made some changes to the make-files.

Thanks so much Erik for the fix! The messages.properties file look
good. I only reviewed the English *messages.properties* file. WPTG
will re-translate the ja and zh_CN files. They will attempt to
leverage existing translation from *JConsoleResources_xx.java*.
I have a comments about another translatability rule that WPTG follows:
By Oracle software development guideline, ALL CAPs or StudlyCaps
strings will not be translated. Examples are:
19 ACTION_CAPITALIZED=ACTION
20 ACTION_INFO_CAPITALIZED=ACTION_INFO
149 MBEAN_INFO=MBeanInfo
150 MBEAN_NOTIFICATION_INFO=MBeanNotificationInfo
151 MBEAN_OPERATION_INFO=MBeanOperationInfo
206 OBJECT_NAME=ObjectName
231 R_FORWARD_SLASH_W_CAPITALIZED=R/W
241 SEQ_NUM=SeqNum
249 SUMMARY_TAB_HEADER_DATE_TIME_FORMAT=FULL,FULL
273 UNKNOWN_CAPITALIZED=UNKNOWN
If any of the above such as ACTION or UNKNOWN needs to be translated,
they should not be ALL CAPS. The translators will not translate those
lines by default.
The translators have the ability to see comments (or special
requests) if a comment line is inserted immediately prior to any of
the resources (each resource string and one comment line immediately
before it is stored in translation memory). If you must leave ACTION
or UNKNOWN in CAPS, you can try to insert comments.However, WPTG does
not guarantee they will be followed.
thanks,
-michael

The patch is for JDK8, but it needs to ported to 7u6 before 5/16.
Thanks!

Changes:
- Moved localization messages to property files, one message per
line, as needed.
- Added '&' to messages so mnemonics could be identified.
- Introduced Message class with static fields corresponding to the
keys in the property files.
- Added map for looking up mnemonics.
Testing:
- Verified programmatically that all the messages and mnemonics are
"compatible" with the previous mechanism, for Chinese, Japanese and
the default locale.
- The intention is to run through the GUI to confirm that everything
looks ok, but I'm waiting for a build.
Other:
- Fixed a typo in the MemoryPoolStat class, the method
getAfterGcUsage returned this.beforeGCUsage instead of
this.afterGcUsage
- When going through all the code I did some minor clean up that
should not impact the program flow:
* removed unused imports.
* inlined temporary variables holding messages.
* removed private member variables that were not accessed.
* removed private methods that were not referenced.
* removed local variables that were not used.
* added generic types where needed.
* static methods are now called statically.
* added suppress serialization warning where it was needed.
* removed suppress serialization annotation where it was not needed.
- In the Message class, the comment "remove? not found in code" will
be removed once I know those message are not needed for 7u6.
