Affects PMD Version:
6.22.0
Rule:
AvoidPrintStackTrace
Description:
Can't detect the case that call printStackTrace() by a method, for example: e.getCause().printStackTrace();. This rule is implemented through xpath search:
<![CDATA[ //PrimaryExpression [PrimaryPrefix/Name[contains(@Image,'printStackTrace')]] [PrimarySuffix[not(boolean(Arguments/ArgumentList/Expression))]] ]]>
AST analyse result:
<PrimaryPrefix FindBoundary='false' Image='' SingleLine='true' SuperModifier='false' ThisModifier='false'> <Name FindBoundary='false' Image='e.getCause' SingleLine='true' /> </PrimaryPrefix> <PrimarySuffix ArgumentCount='0' Arguments='true' ArrayDereference='false' FindBoundary='false' Image='' SingleLine='true'> <Arguments ArgumentCount='0' FindBoundary='false' Image='' SingleLine='true' Size='0' /> </PrimarySuffix> <PrimarySuffix ArgumentCount='-1' Arguments='false' ArrayDereference='false' FindBoundary='false' Image='printStackTrace' SingleLine='true' /> <PrimarySuffix ArgumentCount='0' Arguments='true' ArrayDereference='false' FindBoundary='false' Image='' SingleLine='true'> <Arguments ArgumentCount='0' FindBoundary='false' Image='' SingleLine='true' Size='0' /> </PrimarySuffix>
In the case e.getCause().printStackTrace();, AST chain is: PrimaryPrefix-> PrimarySuffix-> PrimarySuffix(printStackTrace)
Code Sample demonstrating the issue:
try {
doSomething();
} catch(InvocationTargetException e) {
e.getCause().printStackTrace();
}
Expected outcome:
false-negative
