One more problem caused by the patch: java.lang.NullPointerException at org.apache.harmony.archive.internal.pack200.Segment.parseSegmentHeader(Segment.java:856) at org.apache.harmony.archive.internal.pack200.Segment.parseSegment(Segment.java:825) at org.apache.harmony.archive.internal.pack200.Segment.parse(Segment.java:83) at org.apache.harmony.archive.tests.internal.pack200.SegmentTest.testJustResources(SegmentTest.java:41) at java.lang.reflect.AccessibleObject.invokeV(AccessibleObject.java:25)
Thanks, Mikhail 2006/8/10, Mikhail Loenko <[EMAIL PROTECTED]>:
PopulationCodecTest is missing, but there are other new files in the patch. You can see all of them if open the patch with a text editor and seek for "(revision 0)" substring Thanks, Mikhail 2006/8/9, Alex Blewitt <[EMAIL PROTECTED]>: > Weird. I don't know what happened.
