Notable Bug Fixes in JDK 7u5
This list includes some of the notable bug fixes in JDK 7u5.
Note: Some of the following bugs are fixed on a build that was made available after the GA of 7u5. If you experience the following issues, check your installed JDK 7u5 build number. If it is not b06, get the latest JDK 7 update version from OTN.
Area: hotspot/runtime_arguments
Synopsis: Improve VM configuration file loading.
JDK 7u5 contains changes to the default implicit loading of the .hotspot_compiler and .hotspotrc file. For existing deployments which rely on .hotspot_compiler (e.g. to exclude a method from hotspot compilation), an unsupported behavioral option has been provided to simulate the old loading behavior.
Command line options to support old behavior:
-XX:Flags=.hotspotrc
will revert to old behavior for .hotspotrc.
-XX:CompileCommandFile=.hotspot_compiler
for the .hotspot_compiler file.
Area: java/jar
Synopsis: Regression - jar command changes file permissions.
Due to a regression, the permissions of any jar file updated with the jar comm
and are changed to read and write by user only.
This regression affected the Solaris and other Unix platforms. It did not affect the Windows platform.
See 7175845.
The following table lists some of the other bug fixes included in this release:
| Bug ID | Category | Sub_Category | Description |
|---|---|---|---|
| 7166687 | java | classes_net | InetAddress.getLocalHost().getHostName() returns FQDN |
| 7158391 | java | install | Wrong update version text shown in mac JDK installer |
| 7177094 | java | javawebstart/other | Regression: Application fails with "application requesting unrestricted access" error due to cache failure |
| 7177216 | java | java/char_encodings | native2ascii command changes file permissions of input file |
Known Issues
Area: hotspot/compiler
Synopsis: Crash looking up exception handler.
VM exits with Internal Error message "missing exception handler" in sharedRuntime.cpp:728. It could happen when PermGen is full. The recommended workaround is to increase PermGen size (default is 64Mbyte):
-XX:MaxPermSize=256m.
See 7158553.
Area: hotspot/runtime_arguments
Synopsis: JVM not printing unknown -XX options.
If an unrecognized -XX option is supplied to the JVM, it exits. However, the resulting error message does not clearly state that the reason for the JVM exiting is because of the unrecognized option.
See 7162488.
Area: install/au_check
Synopsis: JRE 6ux auto update is broken if JRE 7u4 or JRE 7u5 is uninstalled.
Users may experience difficulty in updating JDK6 Family JREs when JDK7 Family JREs co-exist with JDK6, and are subsequently uninstalled (leaving the JDK6 Family JREs installed).
For example JRE v1.6.0_28 is installed on a system. When JRE v1.7.0_03 or greater is installed then later removed from the same system, the 1.6.0_28 JRE upgrade mechanism is broken.
If this scenario is suspected, use the following workaround:
- Open Control Panel->Java Control Panel
- Click the 'Update Tab'
- Click 'Update Now'
If the user does not have the latest JDK6 Family JRE installed, and no update is detected, the JRE needs to be manually upgraded. To manually upgrade the JDK6 Family JRE, visit the Oracle Technology Network, download and execute the installer for the latest JRE. Alternately, the user can remove the JDK6 Family JRE and install the latest version of JDK7 Family JRE.
