Test tools/pack200/Pack200Test.java fails during compilation:

error: unreported exception Exception; must be caught or declared to be thrown
        jarList.add(Utils.createRtJar());
                                     ^
1 error

TEST RESULT: Failed. Compilation failed: Compilation failed

The problem is that Utils.createRtJar has more wider exception specification than Pack200Test.main.

static File createRtJar(String pattern) throws Exception

and

public static void main(String[] args) throws IOException
