Description of problem:
Switching to Java perspective and opening a Java file causes severe system slow down and java process uses 100% of CPU. Compilation is very slow and throws errors such as "Error cleaning output folder".
I am using separate source and output folders and I have two JRE's installed - the standard ECJ that comes with FC4 and j2sdk-1.4.2_09. The latter is currently set as my default jre.
I try removing ~/.eclipse but this has no effect except to switch me back to resource perspective. I am experiencing frequent crashes as well.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.switch to java perspective
3.open java file and edit
Actual Results: CPU Load very high. Java process using lots of CPU. Compilation slow.
Expected Results: I would expect minimal overhead.
I can't reproduce this. If this is a Sun JVM issue, I can't really help you.
Have you tried upstream Eclipse downloads to see if it is duplicatable there?
You can get a stack trace from the Sun JVM by sending a SIGQUIT.
Use "kill -3 <pid>" where <pid> is the PID of the Java process. This
may be able to give you hints about where the problem may be.
Closing due to lack of response from reporter.
