RFR: 5108778 Too many instances of java.lang.Boolean created in Java application(core-libs)

[Sebastian Sickelmann]

Hello,

Actually I am searching through the JBS for low hanging fruits.
Right now i am looking through the openjdk-sources and try to evaluate
if i can make something about JDK-5108778.

Please find my webrevs for the jdk, jaxp, jaxws and corba repos at:

http://cr.openjdk.java.net/~sebastian/5108778/core-libs/webrev.00/
http://cr.openjdk.java.net/~sebastian/5108778/jaxp/webrev.00/
http://cr.openjdk.java.net/~sebastian/5108778/jaxws/webrev.00/
http://cr.openjdk.java.net/~sebastian/5108778/corba/webrev.00/

I hope for jaxp,jaxws and corba this mailinglist is also the right place.

jdk:
The Boolean constructors are @Deprecated now so that we get
compile-warnings for the uses. See also [0] and [1]

jaxp:
For the change in XBoolean (jaxp) i thought it would be more readable
than the autoboxing solution.

jaxws:
The changes in jaxws are in a generated class. I would love to fix this
in the source, but i have no clue where the real source could be.

corba:
For all calls against
com.sun.tools.corba.se.idl.constExpr.Expression.value(Object) i used the
valueOf solution instead of the autoboxing for better readability.

For some general discussion on regression-tests for this please find the
thread in discuss[0][1] and for the general suggestion to make more
wrapper-type-constructors deprecated find [2] at core-libs-dev.
