[JBoss JIRA] Created: (JBAS-5570) URLDeploymentScanner: relies on FileInputStream finalizer - causes too many open files too easily

URLDeploymentScanner: relies on FileInputStream finalizer - causes too many open files too easily ------------------------------------------------------------------------------------------------- Key: JBAS-5570 URL: http://jira.jboss.com/jira/browse/JBAS-5570 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Deployers Affects Versions: JBossAS-4.2.2.GA Environment: Running on Debian unstable with JDK 1.6_06 Reporter: Toomas Rￃﾃￂﾶmer Assigned To: Ales Justin I'm a JavaRebel developer from ZeroTurnaround and have been debugging an issue with "Too many open files" with JBoss that we got reported against JavaRebel. The problem: Users are getting "Too many open files" exceptions when starting and then using JBoss. The reason: *) JBoss by default has configured a mbean org.jboss.deployment.scanner.URLDeploymentScanner which scans every 5 seconds for changes in the deployment descriptors *) The implementation does a connection = URL.openConnection() and then connection.getLastModified() to check for changes. *) The underlying implementation for regular files is java.io.FileInputStream *) The resource is not explicitly closed as FileInputStream will doit it by itself in the finalizer() *) Handles are freed when GC happens (finalizer logic) I came to this conclusion by getting the number of filehandles (lsof -p <jboss-pid>). Stepping through URLDeploymentScanner and seeing the handles grow by one after every connection.getLastModified(). In all tests the handles grow by one after this call. I also let the handles grow to a few thousand and then attached a debugger and after hitting a breakpoint called System.gc() on the JVM and the number of filehandles nicely went down to ~380 with my deployment folder. Possible solution: Check for the file modification date with explicit closing. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBMICROCONT-156) Look at options for reducing vfs memory usage

by Scott M Stark (JIRA)

Look at options for reducing vfs memory usage --------------------------------------------- Key: JBMICROCONT-156 URL: http://jira.jboss.com/jira/browse/JBMICROCONT-156 Project: JBoss MicroContainer Issue Type: Task Components: VFS Affects Versions: JBossMC_2_0_0 Beta3 Reporter: Scott M Stark Assigned To: Scott M Stark Fix For: JBossMC_2_0_0_CR1 The vfs is eagerly creating URLs for every jar entry touched. This is resulting in a large amount of memory just for Strings. We need to look into reusing the existing name in combination with the root url handler rather than creating new urls to reduce the memory usage. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBMICROCONT-121) Javassist based reflection objects uses the compiler

by Adrian Brock (JIRA)

Javassist based reflection objects uses the compiler ---------------------------------------------------- Key: JBMICROCONT-121 URL: http://jira.jboss.com/jira/browse/JBMICROCONT-121 Project: JBoss MicroContainer Issue Type: Task Components: BeanInfo Affects Versions: JBossMC_2_0_0 Beta Reporter: Adrian Brock The JavassistReflectionFactory builds up a source to compile the method, constructor and field accesors. These implementations are faster than the normal reflection equivalents, but using the compiler is slow.

[JBoss JIRA] Created: (JBREM-661) Allow server sending a stream to the client

This is to request something like java.io.InputStream Client.invoke(java.lang.Object param) that allows for true streaming (like java.lang.Object invoke(java.io.InputStream inputStream, java.lang.Object param) does). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
