Add to OPT_LFLAGS rather than overwrite OPT_LFLAGS when setting /OPT:REF in the make file for Windows. Only set the global shutdown event if the event is created. Unable to build with Java 9 using ant; dropped Ant build files prunsrv stopping with error due to hardcoded timeout. Revered code comments for JRE and JDK locations in the registry. Undefined behaviour in registry.c dwRegKey = dwRegKey++ Add DEBUG and ERROR logging to help diagnose problems when starting a Windows Service. Update the minimum Java requirement from version 5 to 6. Increase minimum Java version to Java 5. Add AArch64 support to src/native/unix/support/apsupport.m4 Compile the Windows binaries with the /DYNAMICBASE and /NXCOMPAT switches. Remove calls to explicit garbage collection during daemon start and stop. Update config.guess and config.sub to add support, amongst others, for the 64-bit PowerPC Little-Endian architecture. Ensure that the PID file on Windows, if used, is readable by other processes. Update Commons-Parent to version 41. Update apsupport.m4 add support for 64-bit PowerPC architectures. Suppress spurious "The data area passed to a system call is too small" error message in the log when procrun fails to stop the service. Move attributions from @author in Javadocs to POM. Enable jsvc to start when running on Java 9. Fix a resource leak opening the JVM configuration file. Improve the jsvc code that restarts the process if the JVM crashes so that if the JVM crashes after a signal has been received to shut down jsvc does not attempt to restart the JVM. Ensure that the child process is started with the correct umask. Correct conflicting information for the behaviour of procrun when using jvm mode. Ensure that, when using procrun in java or exe mode, the service process waits for the stop process to complete before starting clean-up to avoid a crash in the stop process. Enable jsvc to find the jvm when running on AIX. Ensure that procun treats JVM crashes as service failures so the recovery options will apply. Ensure that the //MQ command closes the prunmgr process even if the configuration dialog is open when the //MQ command is used. When looking in the Windows registry for JRE and JDK installation locations, additionally check the registry keys used by IBM provided JREs and JDKs. Do this after checking the keys used by Oracle provided JREs and JDKs. When looking in the Windows registry for JRE and JDK installation locations, additionally check the registry keys used by Oracle provided Java 9 and later JREs and JDKs. Do this after checking the keys used by Oracle provided Java 8 and earlier JREs and JDKs. Add support for Java 9 commoand line arguments to jsvc. Add a restarts options to jsvc to control the number of permitted restarts after a system crash. Remove support for building Procrun for the Itanium platform. Make Windows XP the minimum support target platform. Add support to Procrun for separate JVM options for use when running on Java 9 and above. Fix race conditions in PID file handling in jsvc.
