make/langtools/tools/compileproperties/CompileProperties.java line 187:

So the intended composite predicate here is thought to be
ok == true && contents != null
which is equivalent to
ok && contents != null.
The semantics of the current code are equivalent to just
contents != null
right?

src/jdk.compiler/share/classes/com/sun/tools/javac/comp/Resolve.java line 1316:

Isn't the equivalent statement to
result &= true
just
result
?
