             Bug #: 50520
           Summary: getReaderForText never returns
    Classification: Unclassified
           Product: gcc
           Version: 4.5.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gccbugs.8.enormator@xoxy.net
              Host: x86_64-linux-gnu (Xubuntu 11.04)
            Target: x86_64-linux-gnu


Created attachment 25364
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25364
a minimized code sample that can reproduce the bug

the method getReaderForText in the class DataFlavor seems not to terminate. In
the minimal example program I attached, "initialized" is printed but then
nothing else. The expected behavior would be that this program prints
"initialized" and then prints "reader initialized" and then prints the content
of the clipboard.

exact commandline used: gcj -Wall -Wextra --main=ClipboardReadTest
ClipboardReadTest.java
there are no warnings or errors produced.

The .i file is not attached because the .java file is a minimized test file
which includes no other files.

gcj -v says this:
