Ant build warnings in v1.8.2

[wfordwfu]

I'm in the process of updating my Dockerfile and in my ant build process I'm getting a bunch of warnings. My hope for creating issue is at least some of these look pretty easy to knock out. Java isn't a language I know well, but wanted to make an effort to see if it helps.

A bunch of cases where the Wrapper Class Constructors are called with a deprecation warning. This looks like something deprecated in Java 9, so this one is more of an immediate issue since you all are targeting 17
warning: [removal] Double(double) in Double has been deprecated and marked for removal
warning: [removal] Integer(int) in Integer has been deprecated and marked for removal
warning: [removal] Long(long) in Long has been deprecated and marked for removal

I found something that suggested replacing new Type with Type.valueOf, so running something like this?
find ${I2B2_SRC_DIR} -type f -name "*.java" -exec sed -i
-e 's/new Double(/Double.valueOf(/g'
-e 's/new Integer(/Integer.valueOf(/g'
-e 's/new Long(/Long.valueOf(/g'
-e 's/new Float(/Float.valueOf(/g'
-e 's/new Boolean(/Boolean.valueOf(/g'
{} ;

This shows up each time a build.xml is called. I think this is from my using a later ant version (1.10), but other than this warning everything else seems fine.
[javac] /app/i2b2-core-server/edu.harvard.i2b2.server-common/build.xml:45: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
So maybe something like this to resolve?
find ${I2B2_SRC_DIR} -name "build.xml" -exec sed -i
's/<javac /<javac includeantruntime="false" /' {} ;

There were some others that popped up as well, but I'm not sure how involved they are to fix:
warning: [removal] setSecurityManager(SecurityManager) in System has been deprecated and marked for removal
warning: [removal] SecurityManager in java.lang has been deprecated and marked for removal
warning: [removal] JdbcDaoSupport in org.springframework.jdbc.core.support has been deprecated and marked for removal
