problem to bring up Matlab with 1.4.1 jvm rumtime

###@###.### 2002-04-26

J2SE Version (please include all output from java -version flag):
  java version "1.4.1-beta"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b08)
  Java HotSpot(TM) Client VM (build 1.4.1-beta-b08, mixed mode)

Does this problem occur on J2SE 1.3 or 1.4? Yes / No (pick one)
  No, works fine with JRE 1.3.1_02-b02.


Operating System Configuration Information (be specific):
  Solaris 5.7 Generic_106541-17 sun4u sparc SUNW,Ultra-5_10

Bug Description:
  Problem to bring up Matlab version 6 apps with jsdk 1.4.1,
  only the splash window will open and the process is stuck
  waiting on a read:

  > truss -fp 28492
  > 28492: read(0, 0xFFBEED54, 4) (sleeping...)

Steps to Reproduce (be specific):

  % setenv MATLAB_JAVA /tmp/j2sdk1.4.1/jre
  % setenv _JAVA_OPTIONS -Xusealtsigs
  % /app/bin/matlab6

  If you dont set MATLAB_JAVA and use the default one which
  is jre 1.3.1_02-b02 version, then the Matlab app will come out
  without any problem; vs using 1.4.1, only splash screen comes
  out then sit there and wait.....
