Problems with test methods that have special characters in their name

The following problems exist in the JUnit view (NOT the source editor):

1. The name of a method that contains parentheses is truncated. For example, "with(parens)" will be displayed as "with".
2. When a method that contains parentheses is executed by selecting "Run" from the context menu, the following error occurs: "The input type of the launch configuration does not exist"
3. When a method that contains parentheses is double-clicked, the following error occurs: "Test class not found in selected project"
4. When a method that contains spaces, say "with space", is double-clicked, the following error occurs: "Method 'with' not found. Opening the test class." (Note how the name is again truncated.)

Behavior is the same for JUnit4 and Spock tests. Here is the test code I used:

import org.junit.Test

class MethodNamesTest {
	@Test
	void standard() {}
	
	@Test
	void "stringy"() {}
	
	@Test
	void "with space"() {}
	
	@Test
	void "with(parens)"() {}
}

import spock.lang.*

class MethodNamesSpec extends Specification {
	def standard() {
		expect: true
	}
	
	def "stringy"() {
		expect: true
	}
	
	def "with space"() {
		expect: true
	}
	
	def "with(parens)"() {
		expect: true
	}
}
