----------------------------------
Summary: when ArrayUtils.removeAll meeting 'null' array
Key: LANG-1743
URL: https://issues.apache.org/jira/browse/LANG-1743
Project: Commons Lang
Issue Type: Bug
Components: lang.*
Affects Versions: 3.14.0
Environment: jdk18
Reporter: Wang Hailong
it just throw java.lang.NullPointerException: Cannot invoke "Object.getClass()"
because "array" is null, hope a more propel way to handle this situation, for
example just return null, or raise the illeagleargument exception (the array
must not be null)
the test code is :
{color:#bbb529}@Test
{color}{color:#cc7832}public void
{color}{color:#ffc66d}testRemoveAll_NullArray{color}() {
{color:#808080}// Preparation of the test case
{color}{color:#808080} {color}{color:#cc7832}char{color}[] array =
{color:#cc7832}null;
{color}{color:#cc7832}
{color}{color:#cc7832} {color}{color:#808080}// Invocation of the API
{color}{color:#808080} {color}{color:#cc7832}char{color}[] result =
ArrayUtils.removeAll(array){color:#cc7832};
{color}{color:#cc7832}
{color}{color:#cc7832} {color}{color:#808080}// Final assertion
{color}{color:#808080} {color}assertArrayEquals({color:#6a8759}"Removing
elements from a null array should return null"{color}{color:#cc7832}, null,
{color}result){color:#cc7832};
{color}}
