pingpingy1 opened a new pull request, #289:
URL: https://github.com/apache/commons-bcel/pull/289
In the current implementation of the `createInvoke` method, an NPE is thrown
if the `argTypes` array is `null`. This commit adds a null guard that skips the
for loop if this is the case.
Example:
```java
public static void main(String args[]) {
InstructionFactory factory= new InstructionFactory(new
ClassGen(Repository.lookupClass(Object.class)));
factory.createInvoke("", "", Type.VOID, null, Const.INVOKESPECIAL, false);
}
```
```console
Exception in thread "main" java.lang.NullPointerException
at
org.apache.bcel.generic.InstructionFactory.createInvoke(InstructionFactory.java:643)
at Test.main(Test.java:11)
```
