Here is some explanation for what is happening. When OOo searches for a
suitable JRE it starts the java executable from every JRE it finds, to find out
what system properties it has. Currently the version,vendor,home,and
accessibility property are used. The properties are obtained by running a small
program which is contained in JREProperties.class which is to be found in the
program directory. It gets the properties and prints them using
System.out.println. The values are encoded, so that we are independent of any
encoding of the console. This program is started from with the sunjavaplugin.dll
(jvmfwk/plugins/sunmajor/pluginlib/util.cxx , getJavaProps) by
osl_executeProcessWithRedirectedIO. After the process is started we read the
output stream and the error stream and wait until the process has terminated
(there is a time out). It turned out, that the reading from the output stream
blocked. All data have so far be read. It appeared that the Java process did not
close the stream properly. We also tried out another constellation, where both,
error and output stream are read asynchroniously, after the process had
terminated. That is first, we waited on the process ot finish and then joined on
the reader threads. Again the first thread on which we joint blocked. Probably
in the same ReadFile system call.
This behaviou was caused by using
Toolkit tk = java.awt.Toolkit.getDefaultToolkit();
in JREProperties.class
This call is necessarry to get the system property which tells us if a
accessibiilty bridge is installed. The work around is, that when running on
Windows 98 this call is not made.
Another strange thing is this. When OOo was started the first time, it froze
when searching for JREs. Then after the process was killed and started a second
time then it worked. Or one could run JREProperties in a console and afterwords
start OOo. Then it worked too.
