[maven-release-plugin] prepare release commons-jexl3-3.2

JEXL: preparing 3.2.1

JEXL: add spotbugs:check to default goal

JEXL-342: baseline as test code

JEXL-342: fixed error handling (inner JexlException.Method throw) and reporting (line info)

JEXL: unused import

JEXL-352: restore call to parser.jjtree.reset() after parse

JEXL: add serialVersionUID to exceptions to avoid japicmp complaints in the future

JEXL-351: interpret jexl:{print,include} in template scripts and avoid sandboxed introspection, add test, changes and release notes.

Replace Java 15 with Java 16 in Travis CI.

Merge pull request #57 from csamak/master

More parser compatibility fixes for JavaCC/JJTree

More parser compatibility fixes for JavaCC/JJTree

I'm not sure why STATIC=false was commented out? Without it, generating
the parser with JavaCC does not work.

The Parser constructor taking String throws ParseException (a checked
exception) when generated with JavaCC. I'm not sure why, but the
StringProvider exception does not.

For the pragmaValue changes, unreachable statements were generated. See
http://consoliii.blogspot.com/2014/05/javacc-modern-mode-how-to-resolve.html

With these changes I'm able to use JavaCC and everything passes again.

JEXL-350: release notes, changes, pom

JEXL-350: ensure null can be allowed/blocked as a property to read/write in sandbox, tests, verbosity

Merge pull request #54 from csamak/master

Merge pull request #55 from csamak/typos

Fix small typos in comments throughout

Merge pull request #56 from csamak/obtain-lock

Call Lock.lock before the try

Call Lock.lock before the try

Probably not an issue with the ReentrantReadWriteLock implementation of
Lock.
Other lock usage in Introspector already calls lock before the try.

See:
https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/locks/Lock.html
https://errorprone.info/bugpattern/LockNotBeforeTry

Fix small typos in comments throughout

Use the "modern" parser template

This restores compatibility with JavaCC/JJTree. When set to classic,
ParserGeneratorCC and JavaCC/JJTree generate different output since
TokenMgrError is not supported by ParserGeneratorCC.
