It's possible the install location for Java changed when you upgraded. Does this file exist:
? If not, you need to check the value of wrapper.java.command in $PULSE_HOME/bin/wrapper.conf and make sure it references your new java binary. It may be an explicit path you can update in the file, or may be using JAVA_HOME in which case you can edit the environment variable and then restart (services won't necessarily see environment changes unless you restart).
