How to print failed assertions only without stack trace in soft assertAll() in Selenium?

Is there any way of printing just failed assertions without the entire stack trace when Selenium executes assertAll method?

SoftAssert sa = new SoftAssert();
sa.assertTrue(true,"A failed");
sa.assertTrue(false,"B failed");
sa.assertAll();

So, say this snippet has two assertions either returns true and false. So assertAll() method returns as below.

java.lang.AssertionError: The following asserts failed:
    B failed expected [true] but found [false]

What I want to see in the console log is like.

java.lang.AssertionError: The following asserts failed:
    B failed expected [true] but found [false]

Thank you in advance.

Answer

You can use getMessage() method to print detail message instead of entire stack trace.

Code:

try {
    SoftAssert sa = new SoftAssert();
    sa.assertTrue(true, "A failed");
    sa.assertTrue(false, "B failed");
    sa.assertAll();
} catch (java.lang.AssertionError e) {
    System.out.println(e.getMessage());
}

Output:

The following asserts failed:
    B failed expected [true] but found [false]
