Cannot change default Java version from 11 to 1.8












0















I open new terminal and type java -version and see I have Java 11



java version "11.0.1" 2018-10-16 LTS

Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)


I want default Java version to be 1.8, so I check that I have Java 1.8 installed which I do because I type /usr/libexec/java_home -V and get 



11.0.1, x86_64: "OpenJDK 11.0.1"    /Library/Java/JavaVirtualMachines/openjdk-11.0.1.jdk/Contents/Home

1.8.0_192, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home


so I create new profile with vim ~/.profile and set JAVA_HOME and write and save



#!/bin/bash

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/"


then I close and open terminal and type echo $JAVA_HOME and get correct JAVE_HOME variable 



/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/


but then I type java -version and still get that I have Java 11 



java version "11.0.1" 2018-10-16 LTS

Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)


so I type directly into terminal



export JAVA_HOME="/usr/libexec/java_home -v 1.8


and I see that java version is now Java 1.8



java version "1.8.0_192"

Java(TM) SE Runtime Environment (build 1.8.0_192-b12)

Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)


but If i open new terminal , my version of Java is back to Java 11, so I add the export statement directly to ~/.profile



#!/bin/bash

export JAVA_HOME=`/usr/libexec/java_home -v 1.8


but still the default version of Java when opening a new terminal is Java 11.



So I change profile to 



#!/bin/bash

JAVA_HOME="/usr/libexec/java_home -v 1.8"


and open new terminal still java -v gives Java 11.



How do do I change the default version of Java on OSX from Java 11 to Java 1.8?






bash macos command-line .profile

  • Neither Java itself nor the shell (that finds which java executable to run) cares about JAVA_HOME. Many shell scripts that start Java based applications will pick that environment variable to decide which JVM to start, but if you simply run java then it will run what's on the PATH.

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
