com.github.javaparser.symbolsolver.resolution.typeinference.ControlFlowLogic
Consider Control Flow to determine which statements are reachable.
Except for the special treatment of while, do, and for statements whose condition expression has the constant value
true, the values of expressions are not taken into account in the flow analysis.

A break statement with no label attempts to transfer control to the innermost enclosing switch, while, do, or for statement of the immediately enclosing method or initializer; this statement, which is called the break target, then immediately completes normally.boolean

breakTarget
A break statement with no label attempts to transfer control to the innermost enclosing switch, while, do, or for statement of the immediately enclosing method or initializer; this statement, which is called the break target, then immediately completes normally. A break statement with label Identifier attempts to transfer control to the enclosing labeled statement (ยง14.7) that has the same Identifier as its label; this statement, which is called the break target, then immediately completes normally. In this case, the break target need not be a switch, while, do, or for statement. -
exitTheStatement
A reachable break statement exits a statement if, within the break target, either there are no try statements whose try blocks contain the break statement, or there are try statements whose try blocks contain the break statement and all finally clauses of those try statements can complete normally. -
