问题
While ordinary run under IDEA I've got:
/usr/lib/jvm/java-8-oracle/jre/bin/java ...
Unrecognized option: -MaxMetaspaceSize=256m
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.Process finished with exit code 1
Why can't I add the -MaxMetaspaceSize=256m JVM property?
Additional info:
echo $JAVA_HOME
/usr/lib/jvm/java-8-oracle/lib
sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority
- 0 /usr/lib/jvm/java-8-oracle/jre/bin/java 9 auto mode
1 /usr/lib/jvm/java-7-oracle/jre/bin/java 8 manual mode
The same for javac & javaws, project settings, module, default settings are using jre8 & javac8.
回答1:
The correct name of the parameter is -XX:MaxMetaspaceSize.
回答2:
From java 8, PermSize and MaxPermSize JVM arguments are ignored and replaced by MetaspaceSize and MaxMetaspaceSize.
The Maximum metaspace size can be set using the -XX:MaxMetaspaceSize flag,and the default is unlimited,which means that only your system memory is the limit and for PermSize use -XX:MetaspaceSize.
