Known issuesedit
-
Painless: Any Painless script where a method call resolves a lambda argument to a
UnaryOperator
or aBinaryOperator
type results in anIllegalArgumentException
. This exception results in a compilation error when static types are used, or a runtime error for dynamic types. Use standard procedural statements as a workaround, such asif/else
,while
, andfor
statements.The following example is a
UnaryOperator
type that will result in a failure:List l = ['abc', '123']; l.replaceAll(f -> f.replace('abc', 'doremi');
The following example is a possible workaround:
List l = ['abc', '123']; for (int i = 0; i < l.size(); ++i) { l.set(i, l.get(i).replace('abc', 'doremi')); }
